biomaterial

https://doi.org/10.1351/goldbook.13881
Material exploited in contact with living tissues, organisms, or microorganisms.
Notes:
  1. The notion of exploitation includes utility for applications and for fundamental research to understand reciprocal perturbations as well.
  2. The definition "non-viable material used in a medical device, intended to interact with biological systems" recommended in cannot be extended to the environmental field where people mean "material of natural origin".
  3. This general term should not be confused with the terms biopolymer or biomacromolecule. The use of "polymeric biomaterial" is recommended when one deals with polymer or polymer device of therapeutic or biological interest.
