Abstract

Gold silica nanocomposite-based biosensors are performing well in sensor technology for biosensor development. Due to this biosensor has good selectivity, excellent conductivity, large surface area, efficient enhancement of electron transfer between enzymes and electrodes and good biocompatibility. Therefore, gold silica nanocomposite can be an ideal matrix for immobilization of biomolecules. This review describes the method of synthesizing gold silica nanocomposites and their characterization, interaction with biomolecules and application of gold silica nanocomposites in electrochemical biosensors.

Abstract

The use of gold nanoparticles (AuNP) is an appropriate one in the development of biosensors because it has a unique, strong adsorption, high biocompatibility, and large surface area. AuNPs can be synthesized by various methods with the same synthesis principle by reducing Au3+ to Au. This review explains the various methods of AuNP synthesis and their characteristics, the interaction of AuNP with biomolecules including DNA, and the application of AuNP-DNA bioconjugates in biosensors. Several applications of AuNP-DNA bioconjugates as electrochemical biosensors in the past two years are proposed in this review.
