Herein, doping/decoration of gold nanoparticles (AuNPs) within mesoporous silica-titania nanocomposite is achieved via a facile and co-assembly sol-gel method. Polyethylene glycol is used as a co-structure-directing-agent. For sensing analysis, a mixture of organic dyes i.e., bromophenol blue, pheno...
