Surface Morphologies

Silver (Ag) semishells arrays were fabricated with a seed-mediated growth method by depositing silver films on top of self-assembly close-packed monolayer of SiO2nanoparticles. The surface morphologies and optical properties were characterized using TEM, SEM and UV-Vis spectroscopy. The surface-enhanced Raman scattering (SERS) activities of these nanostructures were investigated using methylene blue (MB) as probe molecule. The enhancement factor was estimated to be as large as 2.05×1010. The results revealed that these Silver nanostructures are good SERS-active substrates.

Diagnostic Applications

Au nanoparticles (NPs) possess unique physicochemical and optical properties, showing great potential in biomedical applications. Diagnostic spectroscopy utilizing varied Au NPs has become a precision tool of in vitro and in vivo diagnostic for cancer and other specific diseases. In this review, we tried to comprehensively introduce the remarkable optical properties of Au NPs, including localized surfaces plasmon resonance (LSPR), surface-enhanced Raman scattering (SERS), and metal-enhanced fluorescence (MEF). Then, we highlighted the excellent works using Au NPs for optical diagnostic applications. Ultimately, the challenges and future perspective of using Au NPs for optical diagnostic were discussed.
