Biological Safety Evaluation of Polyketones as Biomaterials

Biomaterials for clinical applications such as medical and implant devices require evaluation to determine their biocompatibility. This study aimed to evaluate the initial biological safety of polyketone (PK) polymers, which have potential use as biomaterials. It presents results from cytotoxicity and genotoxicity assays and tests determining the levels of skin irritation, sensitization, and acute systemic toxicity caused by PK. The PK polymers showed no cytotoxicity, genotoxicity, allergenicity, irritancy, and systemic toxicity. These results indicate that the PK polymers are potentially biological safe and could be used to replace non-degradable polymeric biomaterials.
