RESEARCH OVERVIEW

Abstract

Chemically modified silk fibroin has gained attention as an important biomaterial due to its biodegradability, abundance of functional groups, and unique mechanical properties. Nitrated silk fibroin contains a large number of functional groups, which enable the binding of metal ions through electrostatic interactions and chelation processes. Based on this binding capacity, silk proteins can be used to develop eco-friendly and effective sorbents for removing heavy metals from aqueous environments. This article presents preliminary research findings regarding the potential of nitrated silk fibroin to sorb (absorb/adsorb) specific metal ions.
