Special Issue Information
Dear Colleagues,
Cold atmospheric pressure plasma (CAP) that is generated in electrical discharges is cutting-edge technology applicable in the food sector, agriculture, medicine, as well as environmental and material technologies due to the unique properties of ionized gas interacting with their surrounding gaseous atmosphere in addition to liquid and solid targets.
Many biochemically active compounds that are formed during plasma treatment also possess disinfecting properties, for example, charged particles (ions and electrons), free radicals, and reactive oxygen and nitrogen species (RONS, including atomic nitrogen (N), nitric oxide (NO), peroxynitrite (ONOO−), and derived species as well as atomic oxygen (O), hydroxyl radical (•OH), superoxide (O2−), and hydrogen peroxide (H2O2), etc.). Plasma technologies are quite effective in decontamination of chemical pollutants and limiting of microbial load, including bactericidal spores, spoilage fungi, and parasites. Thus, they have gained much attention in food-processing sector as a promising alternative tool for maintenance of food product safety and food preservation. Moreover, mild, low-temperature plasma treatment has minimal impact on the nutritional and sensory attributes of food products, lack toxic effects, and can improve the functional and organoleptic properties of food. Many research groups have demonstrated the positive effects of low-temperature plasma processing for the food and biotechnological industries, including in improvement of plant germination and growth, microbial decontamination of food, production lines and tools, modification of food packaging, extension of shelf life, removal of toxins, inactivation of enzymes, and water and wastewater treatment. Plasma treatment is considered a simple, easy to operate, cost-effective, and pro-ecological technology as it significantly reduces both water consumption during production process and spoilage losses with relatively short treatment times. Decontaminative properties of plasma are used in plasma medicine. Plasma treatment can enhance the biocompatibility of materials, improve tissue regeneration, and stimulate living organisms. Plasma is widely used for modifying and shaping the physical and chemical properties of various materials. Engineering process for power technologies, solar energy, batteries, packaging, resurfacing, and printability can be greatly enhanced by plasma treatment steps.
Plasma technology influences many science fields, promoting ecological approach and waste-free economy. Interdisciplinary research contributions representing bio-, food-, agro-, med-, eco-, and material engineering are welcome.

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
