## Summary

Laura Maher, a Medical Device Guru at Greenlight Guru, explains the technical differences between sterilization modalities like gamma radiation and ethylene oxide (EO), including material compatibility issues with silicone and batteries. She details the validation processes, such as bio-burden testing and dose audits, and highlights emerging FDA-recognized modalities like chlorine dioxide that offer safer in-house options. Maher also discusses critical sterility pitfalls, including packaging failures, water system biofilm management, and the risks of bacterial endotoxins from high initial bioburden.
