Dual-responsive water-soluble gold nanocomposite prepared via a new approach

Poly (dimethyl aminoethyl methacrylate-co-spiropyran) (poly (DMAEMA-co-SPEA) was synthesized through RAFT-polymerization. In a novel approach, gold nanocomposite was prepared via an in-situ one-step process in water without using any surfactant or reducing agent. Size and morphology of the gold nanoparticles were investigated by AFM, TEM, EDX and UV-analyses. The prepared gold nanocomposite showed LCST and color changes upon heating and UV-irradiation, respectively.
