The synthesis of oxalate-modiﬁed pyrite/chitosan as an antibacterial composite

The combination of organic and inorganic components has produced bioactive materials with excellent properties. Chitosan is a widely used organic component that has received recognition as a biocompatible material. In contrast, naturally occurring pyrite has so far received limited exposure as a bio...
