LTP Perspectives: Policy, Opportunities, Challenges
Hydrogels in Plasma Medicine – Opening New Possibilities
Plasma treatment of polymers has been widely investigated for some decades, especially to enhance their hydrophilicity, their surface energy or to introduce new functional groups for subsequent processes.
Thanks to the advent of plasma devices working at atmospheric pressure, new avenues have opened in the field of Plasma Medicine - from treating solid polymers in the past, to currently employing hydrogels. In this sense, semi-solid polymers or even polymers in solution are in the limelight for plasma treatment. Hydrogels are a class of soft and elastic materials that consist of a three-dimensional network of hydrophilic polymers capable of holding large amounts of water. Their unique physical and chemical properties make them ideal for a wide range of applications, including biomedical applications, such as drug delivery and tissue engineering. In this context, the great versatility and resourcefulness of hydrogels has recently caught the attention of the scientific community.
In plasma therapies, reactive oxygen and nitrogen species (RONS) generated from plasma sources are pointed out as very important actors, and are responsible of part of the biological response to plasma and plasma treated liquids. It is therefore of interest to understand their distribution in tissues during direct treatment, as well of finding novel ways to deliver them locally when dealing with indirect plasma treatments.
Up to now, hydrogels have been explored with two main objectives of interest in the plasma medicine field. The first is employing hydrogels as surrogates of tissues to investigate the penetration depth of plasmas and distribution of RONS, or as screens for certain RONS during plasma treatment, which imply plasma treatment of gelled or crosslinked hydrogels. In this context, hydrogels can contribute to a better understanding of the interactions between plasma and biological tissues.
Second, plasma treatment of liquids has been widely investigated as transporter of RONS, as they can be injected locally in a minimally invasive approach. In this context, another area of study involves plasma treatment of biopolymers in solution. If the biopolymers are selected with ability to crosslink, they can then form hydrogels to store therapeutic RONS and deliver them to the diseased site in living tissues. Besides, the complexity of biopolymer solutions generates interesting chemistry in their interactions with plasmas, modifying reactivity with regard to conventional ionic solutions and eventually leading to organic oxidized species which might have interest.
In summary, these novel areas of research are paving the way for exciting discoveries in plasma medicine. As the field evolves, hydrogels will likely play an increasingly important role in both new therapeutic applications, as well in helping to better understand the interactions of plasmas with tissues.

Leaders of the LTP Community: Career Profiles
Zoltán Donkó – Mastering both Experimental and Numerical Methods
Zoltán Donkó is a research professor at the Wigner Research Centre for Physics in Budapest, Hungary. He received his university diploma in Electrical Engineering from the Budapest University of Technology in 1989. While still a student, he started working on gas lasers at the Central Research Institute for Physics in Budapest. He received his Cand. Sc degree in 1996 and the DSc (Doctor of Science) title in 2005 from the Hungarian Academy of Sciences.
Early in his career, while investigating noble gas mixture and sputtered metal ion hollow cathode lasers experimentally, his interest has turned to the physics of their active medium, the gas discharge. Guided by this interest, he established computational electrical gas discharge research within the Laser Physics Department. This topic grew rapidly and soon became the central theme of the research group, independent of lasers. His research activities in the past decades included experimental investigations and numerical simulation studies of various types of electrical gas discharges, electron transport phenomena, as well as strongly coupled plasmas, such as dusty and Coulomb plasmas. Over the years, he has developed a zoo of simulation codes implementing different approaches like fluid, hybrid, and fully kinetic models to describe the transport and dynamics of charged particles under a wide range of conditions. These codes have been used in many fundamental studies of various phenomena in low-pressure plasmas, e.g., electron power absorption, the influence of multi-frequency excitation waveforms on discharge characteristics and control of particle properties, frequency coupling effects, the contribution of surface processes to plasma properties. His simulation work goes hand in hand with his experimental research, always looking for possible links. A recent practical result of this approach has been the construction of a series of geometrically symmetric capacitively coupled plasma sources, which allow direct comparison of experimental and numerical results. He continues to broaden his scientific horizon and has recently become involved in studies of atmospheric pressure and magnetized plasma sources as well.
In addition to his research activities, Zoltán is actively involved in the training and mentoring of students and young researchers, from high school level to post-docs. He regularly gives introductory university courses on gas discharge physics and particle-based simulations. His recent lectures are highly appreciated by students from all over the world.
Zoltán has served in the editorial board of Plasma Sources Science and Technology from 2017 and has been Associate Editor of the journal from 2021 to 2023. He served in the scientific committees of some of the most important conference series of his research fields. In Hungary, he participated in the organization of the Europhysics Conference on the Atomic and Molecular Physics of Ionized Gases (ESCAMPIG) in Lillafured in 2000, the Colloquium Spectroscopicum Internationale in 2009, the Strongly Coupled Coulomb Systems (SCCS) in 2011 in Budapest, and the Central European Symposium on Plasma Chemistry (CESPC) in Balatonalmadi in 2013.
During his more than 30-year academic career, Zoltán has received several prestigious awards, including the William Crookes Prize (2010) for his contributions to the understanding of the effect of elementary processes on the properties of gas discharges and strongly coupled plasmas, the Schmid Award of the Hungarian Physical Society (1998), and the Award of the Hungarian Academy of Sciences (2017). He has been a visiting scholar at Boston College, USA, visiting professor and specially appointed professor at Osaka University, Japan, and a Mercator Fellow at Ruhr University Bochum, Germany, for several years.
Although his academic activities could fill his entire life, he is careful to balance his professional and personal life. He is a passionate and regular badminton player. Many in the LTP community have had the opportunity to play badminton with him during conferences or scientific visits. He is an enthusiastic nature photographer. Every year he devotes a few weeks to this passion, kayaking in the hidden channels of Lake Tisza and capturing the beauty of nature. About Life, the Universe and Everything, he shares much of the views of the depressed android from his favorite novel, The Hitchhiker’s Guide to the Galaxy by Douglas Adams.
We, his former students, and current colleagues and friends, are grateful to him for inducing us to this exciting field and for his continued support in our careers.

Community Initiatives and Special Issues
Special Issue of PSST on Fundamentals of Atmospheric Pressure Plasma Interactions with Complex Surfaces
The use of atmospheric pressure plasmas (APPs) in healthcare, energy storage, chemical conversion and environmental stewardship often results in plasma interactions with complex surfaces. Complex surfaces entail interfaces with the APP that may be, non-planar, porous, reactive, deformable or liquid. The APP interacts with these interfaces through the plasma produced reactive fluxes (e.g., radical, hot particles, electrons, ions, photons) incident onto the surface that both modify the surface and feedback to the plasma through, for example, charging, secondary processes, changing reaction probabilities or evaporation.
A Special Issue of Plasma Sources Science and Technology is devoted to papers describing experimental, computational and theoretical investigations of APPs interacting with complex surfaces having an emphasis on the fundamental plasma and surface properties and processes occurring during these interactions. This emphasis includes, but is not limited to, plasma self-organization at interfaces, species transport and control, radiation transport, diagnostics and new computational techniques, and fundamental data needed to understand plasma-surface interactions under these conditions.
While the issue is focused on the more unique aspects of APP interactions with complex interfaces with inherent short temporal and spatial length scales, potential instabilities and localized coupling between plasma properties and the interfacing surface properties, contributions addressing a broader range of conditions (such as pressure) that retain the characteristics of APPs or contribute to advancing our understanding of unique APP interactions with surfaces are also welcome.
Articles should be submitted via the Web using the PSST online submission form. Where the form asks for ‘Article Type’ please select ‘Special Issue Article’. Then select ‘Special Issue on Fundamentals of Atmospheric Pressure Plasma Interactions with Complex Surfaces’ in the ‘Special Issue’ drop down box that appears.
The deadline for submissions is 31 May 2023. PSST is able to publish special issues incrementally. This means that articles submitted early will be published as soon as they are accepted and prepared for publication, without being delayed waiting for other papers in the collection.

Research Highlights and Breakthroughs
Hybrid Plasma–Liquid Functionalization for the Enhanced Stability of CNT Nanofluids for Application in Solar Energy Conversion
We have used plasma-induced non-equilibrium electrochemistry to functionalize the surface of macroscopic ribbon-like assemblies of carbon nanotubes (CNTs) and enhance their dispersion within ethylene glycol for application in solar-to-thermal energy conversion. In particular, the nanofluids with CNTs that showed a combined nitrogen-based and high oxygen-based functionalisation—the “plasma–liquid” samples—performed exceptionally well. These showed a reduction in the contact angle from 84° to 35°, along with corresponding improvements in hydrophilicity and dispersion, leading to the enhance-ment of the absorption coefficient, reaching values greater than 2 cm−1 at 600 nm, with much greater values above 5 cm−1 observed at the logarithmic Van Hove peak at 256 nm. Solar thermal conversion experiments show that this “plasma–liquid” additive results in the greatest temperature increase—to above 40 °C—as well as a solar–thermal conversion efficiency of 50%. The long-term performance of the treated nanofluids was assessed, with values of 80% incident radiation absorption retained after 67 months of storage, with only a brief manual shake required to fully redisperse the material prior to UV–Vis measurements, highlighting the readiness for industrial application.

Arc Plasma at Pressures above Atmospheric Helps Improve the Energy Cost and Production Rate of Nitrogen Fixation into NOx
Many factors hinder the application of plasma-based nitrogen fixation (NF) for fertilizer production, e.g., the commonly observed inverse correlation between energy consumption (EC) and production rates (PR), or the necessity to enhance the selectivity towards NO2 with is the desired product for a more facile formation of nitrate-based fertilizers. We investigated the use of a rotating gliding arc plasma for NF at elevated pressures (up to 3 barg), at different feed gas flow rates and composition. We demonstrate a dramatic increase in the amount of NOx produced as a function of increasing pressure, with PR reaching as high as 69 g/h in oxygen-enriched air. Notably, this corresponds to EC of 1.8 MJ/(mol N) (the lowest reported for this high PR) and a nearly exclusive production of NO2. By comparing the kinetic rate coefficients of the Zeldovich mechanism (direct and back reactions) and the oxidation of NO to NO2 as a function of pressure, we can ascribe this improvement not only to the enhanced thermal Zeldovich mechanism, but also to the increased rate of NO oxidation due to the elevated pressure. Altogether, this work identifies pressure as an important parameter to enhance the plasma NF performance.

Current State of Cold Atmospheric Plasma and Cancer-Immunity Cycle: Therapeutic Rele-vance and Overcoming Clinical Limitations Using Hydrogels
Cold atmospheric plasma can be used to selectively kill cancer cells. However, its true promise in oncology lies in the fact that plasma treatment could help drive and enhance anti-tumor immunity to ensure systemic and lasting therapeutic effects. In this review, we offer a critical, comprehensive, and tabular summary of different mechanisms by which plasma treatment (direct or indirect) could promote anti-tumor immunity. More specifically, we discuss: 1) induction of immunogenic cell death, 2) oxidative post-translational modification of tumor and its microenvironment, 3) epigenetic regulation of aberrant gene expression, and 4) enhancement of different immune cell functions. These insights could help the rational development of efficient (combinatorial) treatment strategies and meaningful clinical implementation of plasma.
Related to this, we discuss the clinical limitations of plasma associated with current treatment modalities (direct treatment and plasma-treated liquids). We then put into perspective plasma-treated hydrogels (PTH) as a novel modality that could both broaden and improve the clinical utility of plasma. On one hand, PTH could enable minimally invasive and high local delivery of reactive species to deeper tumor tissues. On the other hand, PTH may offer a way to combine plasma treatment with hydrogel-based drug delivery and tissue engineering for more advanced treatment strategies. Finally, we summarize the current knowledge on PTH and offer some practical considerations and future research directions related to this emerging research field.

Generation of Neutral pH High-strength Plasma-activated Water(hs-PAW) from a Pin-to-water (P2W) Air Discharge and Its Bactericidal Activity on Multidrug-resistant Pathogens
In recent decades, multidrug resistance (MDR) in bacterial infections has become a looming health and economic burden. MDR severity exaggerates hospital infection rates, especially for patients with an impaired immune system. As a result, lowering the bacterial burden is of significant concern. Plasma activated water, with its rich and diversified aqueous reactive nitrogen and oxygen species (RONS), is emerging as an alternative green technique in biomedicine.
This work investigated a Pin-to-Water (P2W) air discharge to generate a neutral pH high strength PAW (hs-PAW) and its bactericidal action without using any expensive carrier gas. The factors influencing PAW strength were explored and improved to generate hs-PAW, including water type, PAW temperature, plasma enclosure, and activation time. The chemistry was established by choosing a neutral pH and chilling the water to generate stable hydrogen peroxide. A design intervention in the plasma enclosure induced a higher nitrite concentration and made a stable higher PAW species of biomedical importance. Analysis of the metabolic assay and confocal images confirms the application of hs-PAW against MDR bacterial pathogens (hypervirulent Klebsiella pneumonia and Methicillin-resistant Staphylococcus aureus). This work demonstrates a simple P2W discharge reactor for generating PAW disinfectant liquid to address MDR pathogens, a technique that can be easily scalable for real-world medical applications.

Hybrid Plasma Generation over Liquid
Hybrid plasma refers to the combination of two or more types of plasma sources to create a new type of plasma. The concept is based on the idea that combining different plasma sources can lead to new and unique plasma characteristics that can be utilized for specific applications. In this experiment, hybrid plasma was generated over liquids by combining gas discharge and electron beam plasmas. This experimental study investigates the ability of hybrid plasma generation over a special liquid mixture of vaseline and lecithin. The apparatus used consisted of radio frequency power connected to an electrode disc that was inserted into the liquid mixture placed in a vacuum chamber. The results show that, the plasma cloud formed uniformly around the liquid layer and was stable during the experiment. After the experiment, the droplets of water on the petri-dish used for the experiment were observed to be more viscous than on the other petri-dish not used. The potential applications of hybrid plasma generation over liquids involve the use of fundamental physics laws, including the laws of thermodynamics, electrodynamics, and plasma physics. These laws are crucial to the understanding of plasma generation, its applications, characteristics, and interactions with the liquid droplets or films.
