“…[165] Different packaging materials including polyethylene, polypropylene and nylon loaded with microbial pathogens have shown no change in the physical properties after treatment with low pressure plasma. [166] Recent studies have shown of sterilized products. [167] Another attractive advantage of CAP over conventional sterilization is cost-efficiency.…”

Tissue products are susceptible to microbial contamination from different sources, which may cause disease transmission upon transplantation. Terminal sterilization using gamma radiation, electron‐beam, and ethylene oxide protocols are well‐established and accepted, however, such methods have known disadvantages associated with compromised tissue integrity, functionality, safety, complex logistics, availability, and cost. Non‐thermal (cold) atmospheric pressure plasma (CAP) is an emerging technology that has several biomedical applications including sterilization of tissues, and the potential to surpass current terminal sterilization techniques. This review discusses the limitations of conventional terminal sterilization technologies for biological materials, and highlights the benefits of utilizing CAP.

“…Adequate processes are efficient, do affect only slightly the bulk material, are environmentally sound, do not produce toxic by-products, and are fast and cost-effective. Therefore, this kind of method is regarded as a green technique and even as the most promising bio-decontamination technique [2][3][4].…”

The main objective of this work was to fully understand the bio-decontamination process in a reduced-pressure oxygen plasma. Gram-negative Escherichia coli species was chosen as the target microorganism in this test. The comparison of decontamination efficacy between plasma total and UV radiation individually under various treatment parameters and tests of DNA agarose electrophoresis were made to evaluate the inactivation effect of UV radiation. The quantity of protein leakage and the concentration of malondialdehyde (MDA), which are markers of the end products of lipid peroxidation, in bacterial suspension after treatment were determined to estimate the contribution of both charged particles and free radicals for bacterial death. In addition, a scanning electronic microscope was used to visualize the plasma effect on microorganisms. The results showed that the essential action of the oxygen plasma on Escherichia coli is believed to be attributed to the fast and intense etching on cell membrane by electrons and ions. Attacks on polyunsaturation fatty acid (PUFA) in the cell membrane by oxygen free radicals and the destruction of the DNA in the cell by UV radiation are accessorial during an effective decontamination process.

“…Several papers deal with decontamination of food packaging materials by NTP generated under low pressure as [21][22][23][24][25]. Following works use NTP in more economically and easier-to-use form at atmospheric pressure, for example, the decontamination of polymer foils [26], plastic tray, aluminum foil and paper cup [27], PET lm [28], dried laver [29], shell eggs [30], or sealed packages [31].…”

e inactivation e ect of the combination of nonthermal plasma and hydrogen peroxide aerosol for the microbial decontamination of inner surface of cylindrical container buckets is studied on one bacterial and seven lamentous micromycete species and on airborne-contaminated cups. While the decontamination by single nonthermal plasma or hydrogen peroxide is not observable after 120 s, the strong decontamination by their combination occurs after 30 s of exposure. Moreover, observed total elimination of airborne contamination of plastic cups predetermines this method as a suitable alternative to the currently used method based on the application of hydrogen peroxide.
