Research Topics


Field medical use of many surgical instruments, including delicate instruments such as endoscopes, requires cold sterilization, cold being defined as a temperature range between ambient (25C) and moderately elevated (up to 60C). Because of hazards in transporting and using ethylene oxide, it has been eliminated from field medical use; and glutaraldehyde, a disinfectant which has many undesirable characteristics involving logistics support, user sfaety and product effectiveness, is currently being used as a replacement. Required is a safe and effective dry powder sterilant that can be added to water to effect the cold sterilization of instruments. It should be packaged as an ineret powder that can be safely and efficiently transported and stored; and the waste solution should not pose a toxic hazard to users.
