Optimum Growth Time in Agpt Nanofern preparation for An Enormous Surface-Enhanced Raman Scattering Intensity

Norhayati Abu Bakar

Abstract


Surface-enhanced Raman scattering (SERS) is a phenomenon where the signal of the Raman spectrum of an analyte increased due to a plasmonic effect of metal nanoparticles. This phenomenon is potentially be implemented in biosensor application to detect the presence of a molecule in blood and urine. This paper reports a study on bimetallic thin film of argentum-platinum (AgPt) nanoferns as a SERS substrate for detection of creatinine. Nanofern-shaped AgPt was prepared directly on ITO surface using liquid phase deposition technique. The growth time of the AgPt preparation was varied from 5 to 60 minutes to study the effect of growth time towards deposition of AgPt nanofern on the surface. This sensitivity of SERS measurement that studied by comparing the Raman spectra of creatinine on ITO surface and creatinine on AgPt surface. It observed that the sensitivity of the spectroscopy system towards creatinine molecule detection is dependent on the morphology structures of AgPt substrate.
