“…SERS has shown great potential in the fields of surface science, medicine, biosensing, and food safety due to its high sensitivity, selectivity, and reliability. − At present, surface-enhanced Raman spectroscopy substrate materials are mainly dominated by precious metal nanomaterials with various morphologies. When the molecules to be tested are adsorbed on the rough surface of a precious metal, the Raman signals of the probe molecules are enhanced by the local electric field generated by local SERS on the precious metal surface.…”

In this study, a simple, green, and low-cost room temperature synthesis of broccoli-like silver nanoflowers (AgNF) with a particle size of about 300−500 nm was developed using plant-derived caffeic acid as a reducing agent and polyvinylpyrrolidone as a dispersant under ultrasound assistance. The flower clusters covered by small nanocrystals of 20−50 nm significantly enhance the electromagnetic field signals. AgNF was deposited on the surface of silicon wafers as a surface-enhanced Raman spectroscopy sensor for the detection of probe molecules such as rhodamine 6G (R6G) and malachite green with high sensitivity, homogeneity, and reproducibility. AgNF was deposited on cotton fabrics in the form of composites to catalyze the degradation of dye pollutants such as R6G, MG, and methyl orange in the presence of sodium borohydride. 0.1 g of AgNF/cotton fabric could assist 15 mmol/L NaBH 4 to achieve over 90% degradation of various dyes as well as a high concentration of dyes in 12 min with good reusability and recyclability. The AgNF synthesized in this work can not only monitor the type and amounts of pollutants (dyes) in wastewater but also catalyze the rapid degradation of dyes, which is expected to be valuable for industrial applications.

Label-free SERS ultrasensitive and universal detection of low back pain fingerprint based on SERS substrate

Abstract: A SERS biosensor, in conjunction with principal component analysis, was used to detect substance changes in the process of fasciitis. Changes in the concentrations of tryptophan, phenylalanine and glycogen were found to be the most obvious in the process of fasciitis.
