Nanocomposites consisting of bacterial cellulose (BC) and gold nanoparticles (AuNPs) were successfully fabricated using a facile one-step photoinduction method. Well-dispersed AuNPs were in-situ synthesized on the network of BC hydrogels in the presence of tetrachloroauric (III) acid solution under a xenon light source. BCs were treated with different concentrations of gold ions. The optical features...
Flexible SERS active substrates were prepared by modification of silk fabrics with gold nanoparticles. Gold nanoparticles were in-situ synthesized after heating the silk fabrics immersed in gold ion solution. Localized surface plasmon resonance (LSPR) properties of the treated silk fabrics varied as the concentration of gold ions changed, in relation to the morphologies of gold nanoparticles on silk...
