Plasma Sterilization of Biopolymers
 Hantáková, Michaela ; Slámová, Jitka (oponent) ; Krčma, František (vedoucí práce)
This thesis is dialled to studying the plasma sterilization of biopolymers using lowtemperature non-equilibrium plasma of electrical discharges for the medical applications. The dielectric barrier discharge was generated in atmospheric gases based mixtures at atmospheric pressure. The sodium glass plates were used as dielectric to ensure the discharge operation in the atmospheric pressure glow mode. The effect of various physical parameters of the plasma as well as the stress factors on the sterilization efficiency were studied. The gram-positive bacteria Micrococcus Luteus and gram-negative bacteria Serratia Marcesceus were used as the model organisms under the current study. The bacterial samples were deposited on the Whatman 1 paper as well as on the biopolymer fibres made of P3HB (trade mark Hydal of company Nafigate Corporation). and then exposed to the plasma. The experimental results are evaluated by the available microbiological analysis methods. The samples were after exposed directly to the plasma. Experimental results were evaluated by the accessible microbiologic techniques. The results confirmed the plasma sterilization success; the best results were obtained using sterilization by DBD generated in wet air enriched by oxygen. The detailed research of sterilization using the low temperature non-equilibrium plasma will be a subject of consequent master Thesis.
