In order to protect humans from potential biological risks arising from the use of medical devices, international standards, national standards and guidelines provide guidance on the overall evaluation of various medical devices and the biological evaluation of the development process. As a crucial part of biological evaluation, in vitro cytotoxicity evaluation often provides important guidance for how to conduct the next biological evaluation. The International Organization for Standardization (ISO) and the United States Pharmacopeia (USP) have established special evaluation methods for cytotoxicity testing (ISO 10993-5, ISO 7405, USP General Chapter 87). https://biocoating.cd-biop...
