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 … Show more
