Abstract:Surface-Enhanced Raman Spectroscopy is a powerful technique that boosts the distinctive fingerprint signals of molecules, making them more accessible for analysis. It utilizes metallic nanoparticles, acting as amplifiers, to greatly enhance the signals emitted by the molecules. This study aimed to explore the SERS potential of gold nanoparticles (AuNPs) with different geometries using a non-resonant molecule, 4-MBA. Nanospheres (14±2 nm), nanorods (11±2 nm x 50±7 nm) and nanostars (38±4 nm) were synthesized vi… Show more
