Fibre-optic pH sensor based on silver nanoparticles for Harsh Environments

Research output: Contribution to conferencePoster

Abstract

The aim of the fabrication and characterization of a surface plasmon resonance (SPR) pH sensor using coatings of silver nanoparticles on optical fibre which can function in harsh environments. The objective is to determine the optimum conditions for the synthesis of silver nanoparticles which are stable and decorate them on an optical fibre to form a pH sensor. This will unveil the sensitivity of the pH sensor with regards to the minimum particle size of silver nanoparticle and the effect of the multilayer coating.
SPR has become an increasingly exploited technology for the detection and analysis of chemical and biological compounds. Silver nanostructured films fabricated by sol-gel techniques has been observed to exhibit a strong localized surface plasmon resonance (LSPR) at a wavelength around 400 nm [1-3]. The spectral position of LSPR is sensitive to factors such as pH and the size of the nanoparticles.
Although the synthesis of silver nanoparticles and characterization using various analytical techniques have been widely studied, the sensitivity of coating with respect to the change in pH of the solution is still required to advance the current state of knowledge. In this study, the coating of the silver nanoparticles on fibre optic will be prepared by chemical reduction involving different concentrations of silver nitrate, reaction time by dip coating method. The absorbance and light scattering behaviour of silver nanoparticles will be characterized using UV-visible spectrophotometer and the particle size will be characterised by using SEM. The expected result will be used to determine the size range of the nanoparticles and the stirring time that can provide stable particles which exhibit SPS.
