Transfer of Dye Monolayers onto Silver Metal Films Formed by Photolysis of Silver Salt of Carboxymethylcellulose

Abstract

A bright silver mirror was formed by photolysis of silver salt of carboxymethylcellulose with 253.7 nm light. The silver metal film was proved to be useful for the substrate to deposit dye monolayers. Fluorescence quenching of rhodamine B on the silver metal film was interpreted in terms of excitation energy transfer.

Preparation of nanosized gold particles in a biopolymer using UV photoactivation

“…and the protective action and reducing properties (both chemical and photochemical) of all these types of carbohydrates and also carbohydrate-based dendrimers are known [18][19][20][21]. The photoreduction usually occurs after the formation of the complex with the functional groups present in the polymer.…”

Biological synthesis of silver and gold nanoparticles using apiin as reducing agent

“…Liz-Marzan and co-workers have shown that triangular/hexagonal Au nanoparticles (NPs) are preferentially absorbed on a thin film polyelectrolyte compared to their spherical counterpart [17]. Photochemical reduction of silver nanoparticles is prepared using high molecular weight carbohydrate and also carbohydrate-based dendrimers as reducing and stabilizing agent [18,19]. Later, Esumi et al have reported the preparation of gold-chitosan nanocomposites and its biological applications [20].…”
