Fluorescence microscopy and photodielectric characterization studies of the composite films of polyvinyl alcohol and tryptophan functionalized silver nanoparticles

Abstract

Fluorescent nanocomposite films were prepared by solution mixing of polyvinyl alcohol (PVA) and tryptophan amino acid functionalized silver (AgTrp) nanoparticles. Tryptophan absorbs in the UV part of the electromagnetic spectrum and the synchrotron excitation deep-ultraviolet (DUV) fluorescence imaging was used to follow the distribution of AgTrp nanoparticles within the polymer matrix. The study showed changes in the PVA morphology after its mixing with AgTrp and pure tryptophan (the pure and hybrid PVA-tryptophan films are used as reference
