The reducing property of collagen was employed for the synthesis of gold nanoparticles (AuNPs) without the use of any toxic chemicals. The morphology of the resulting AuNPs-collagen particles appeared in spherical and triangular nanoprisms with sizes ranging from 30-60 nm, as observed in TEM results. Increasing the synthesis temperature led to the growth of AuNPs. Surface-enhanced Raman Spectroscopy studies revealed that amide I and carboxylic acid group vibrations indicated collagen binding to the Au surface through these groups. The AuNPs-collagen nanocomposite was tested for its antimicrobial properties against eight different microorganisms and it exhibited antibacterial properties solely against the Gordonia rubripertincta bacterium.
