Enhanced Raman Scattering

While surface-enhanced Raman spectroscopy (SERS) has been attracting a continuously increasing interest of scientific community since its discovery, it has enjoyed a particularly rapid growth in the last decade. Most notable recent advances in SERS include novel technological approaches to SERS substrates and innovative applications of SERS in medicine and molecular biology. While a number of excellent reviews devoted to SERS appeared in the literature over the last two decades, we will focus this paper more specifically on several promising trends that have been highlighted less frequently. In particular, we will briefly overview strategies in designing and fabricating SERS substrates using deterministic patterning and then cover most recent biological applications of SERS.

High Yields

The raspberry-like gold nanoparticles were synthesized with high yields following reduction with hydrochloroauric acid and peptide (Boc-Leu-Aib-Trp-OH) in methanol solution. Peptide acted as reducing agent. The prepared raspberry-like gold nanoparticles are effective application for surface-enhanced Raman scattering in ascorbic acid (Vc). Here, we also demonstrate the effective catalysts of raspberry-like gold nanoparticles for the activation and reduction of methylene blue in the presence of NaBH4.

Enhanced Raman Scattering

An efficient surface-enhanced Raman scattering substrate based on silver nanoparticles/silicon pyramid arrays structure is theoretically investigated and experimentally demonstrated. The electric field distributions using finite-element-method are calculated. The surface-enhanced Raman scattering behaviors of sensitivity, uniformity and stability are emphatically discussed and compared by the detection of crystal violet. These theoretical and experimental results reveal that the silver nanoparticles/silicon pyramid arrays substrate is expected to be an effective surface-enhanced Raman scattering platform for label-free sensitive surfaceenhanced Raman spectroscopy detection in areas of biotechnology, medicine and food safety.
