Abstract:
This paper reports a study to detect urea by a homemade surface-enhanced Raman Spectroscopy (SERS) sensor using gold- nanoseeds (AuNS). The nanoseeds were prepared by the first of two steps of the seed-mediated technique where the sizes of the nanoseeds were controlled through the heat treatment periods. It was demonstrated that gold- nanoseeds (AuNS) with the averages sizes of 15-20 nm can be utilized to enhance the Raman peaks intensities of urea. The enhancement intensities of the Raman peaks are linear with the urea concentrations where the lowest urea concentration that was detected using AuNS from this study is 0.0901 g/L.
