Growth of silver nanoparticles on unpolished silicon substrate by used of microwave-assisted technique to enhance the Raman spectrum of glucose

Abstract Silver nanoparticle is useful metallic due to plasmonic property. One of the most important application silver enhancing Raman spectrum using so-called surface-enhanced spectroscopy (SERS). Mostly, researchers synthesize colloidal nanoparticles and deposite on substrate form SERS substrates. In this work, we simplified synthesis by use microwave. We have successfully grown unpolished silicon single step microwave-assisted technique. The has micro-size chambers that are for measurement. were approximately 88 nm in diameter. Our experiment corn syrup revealed our enhance peaks spectra glucose galactose more than 16 times.
