Synthesis and Characterization of Bovine Serum Albumin‐Conjugated Copper Sulfide Nanocomposites

Abstract

A simple biomolecule‐assisted solution route was developed to synthesize Bovine Serum Albumin‐conjugated copper sulfide (CuS/BSA) nanocomposites, directly using copper salts and thioacetamide (TAA) as the starting materials with a zwitterionic surfactant Bovine Serum Albumin (BSA) as foaming and stabilizing agent. The CuS/BSA nanocomposites have been characterized by UV, TEM, Zeta, DLS, XRD, and FTIR. The results indicate that the as‐prepared CuS/BSA nanocomposites are approximate sphere with a size distribution from 10 to 35 nm in diameter and good dispersibility, depending highly on concentration of BSA concentration. These protein‐assisted synthesized nanocomposites have a great potential application in biomedical engineering and microelectronics.
