Bioshell 氧化钙 (BiSCaO) 源自扇贝壳，经过热处理后表现出广泛的杀菌活性。 BiSCaO水是将BiSCaO粉末加入水中后收集水层而制成的消毒剂，无色透明，pH为12.8。我们比较了市售 BiSCaO 水、乙醇、次氯酸钠、次氯酸和过氧化氢溶液作为灭菌剂的效用，以实现外科口罩和 N95 口罩的重复使用。使用被正常菌群污染的外科口罩和 N95 口罩评估每种消毒剂的杀菌效果。结果表明，BiSCaO水对受污染的聚丙烯口罩具有优异的消毒活性，并且对无纺布口罩结构的不利影响最小。
Bioshell calcium oxide (BiSCaO) is derived from scallop shells and after heat treatment exhibits broad microbicidal activity. BiSCaO Water is a disinfectant prepared by collecting the aqueous layer after adding BiSCaO powder to water, is colorless and transparent, and has a pH of 12.8. We compared the utility of commercially available BiSCaO Water, ethanol, sodium hypochlorite, hypochlorous acid and hydrogen peroxide solutions as sterilization agents to enable the reuse of surgical and N95 face masks. The microbicidal efficacy of each disinfectant was evaluated using pieces of surgical and N95 face masks contaminated with normal bacterial flora. The results suggest that BiSCaO Water has excellent disinfection activity toward contaminated polypropylene masks and has minimal adverse effect on the structure of non-woven masks.
