Biological evaluation for nanomaterial medical devices--Testing andcharacterization methods for silver nanoparticles and ions released fromsilver nanoparticle containing dressing
YY/T 1863-2023 Biological evaluation for nanomaterial medical devices - Testing and characterization methods for silver nanoparticles and ions released from silver nanoparticle-containing dressing
1 Scope
This document specifies the test methods to evaluate the silver nanoparticles and ions released from silver nanoparticle-containing dressings in the release medium, as well as the separation, determination and characterization of silver nanoparticles and ions in the release fluid.
This document is applicable to the evaluation of the release characteristics of silver nanoparticles and ions of silver nanoparticle-containing dressing in contact with body surface wounds.
