The ozone density generated from the plasma source of surface microdischarge (SMD) in plasma sterilizers has been decreased by 70%, resulting in a density of less than 0.05 ppm, whereas the densities of OH and H2O2 have significantly increased due to UV-C dissociation with a high absorption cross section for ozone gas. The ozone density was calculated by estimating the oxygen atoms using the major reaction equations for ozone formation and dissociation, and measurement of the time constant of diffusion decrease (τdif). The ratio of the O density for the O3 density generated from the plasma source decreased as the distance between the ozone measurement locations and the plasma source increased. In particular, the excited state density of atomic oxygen O(1D) could be estimated at the downstream region of the air outlet in this study.","PeriodicalId":53607,"journal":{"name":"Plasma Medicine","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67349179","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The molecules can effectively decrease side effects of the drug and increase their targeting. Air microplasma discharge was used to treat rat intestinal cells to induce absorption of fluorescein isothiocyanate-dextran with a molecular weight of 150 kDa (FD-150). Absorption of FD-150 was confirmed by observation using fluorescence microscope. Efficiency of absorbance was estimated by a plate reader, and the viability of the cells was measured by a cell counter. The viability of the cells was proportional to the decrease in treatment time and the increase in treatment distance from the microplasma electrode. The absorption of FD-150 was found to be proportional to the increase in time and distance. No improvement in absorption or viability was observed during the incubation time. Cell treatment by the plasma-treated medium showed a lower absorption of FD-150 than direct treatment but the same cell viability. Concentration of ozone in the gas phase and OH radical in the liquid phase were observed.","PeriodicalId":53607,"journal":{"name":"Plasma Medicine","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67349672","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
