Silver nanocube on gold microplate as a well-defined and highly active substrate for SERS detection.
Strong enhancement and good reproducibility in Raman signals are two major requirements for a surface-enhanced Raman scattering (SERS) substrate to be used for sensitive detection of an analyte. Here we report a new type of SERS substrate that was fabricated by depositing a Ag nanocube (AgNC) on the surface of a Au microplate (AuMP). Owing to the strong and reproducible hot spots formed at corn...
متن کاملSilver Nanoparticle-Embedded Thin Silica-Coated Graphene Oxide as an SERS Substrate
A hybrid of Ag nanoparticle (NP)-embedded thin silica-coated graphene oxide (GO@SiO₂@Ag NPs) was prepared as a surface-enhanced Raman scattering (SERS) substrate. A 6 nm layer of silica was successfully coated on the surface of GO by the physical adsorption of sodium silicate, followed by the hydrolysis of 3-mercaptopropyl trimethoxysilane. Ag NPs were introduced onto the thin silica-coated gra...
متن کاملSoy protein–nanocellulose composite aerogels
Organic aerogels based on two important and widely abundant renewable resources, soy proteins (SP) and nanofibrillar cellulose (NFC) are developed from precursor aqueous dispersions and a facile method conducive of channeland defect-free systems after cooling and freeze-drying cycles that yielded apparent densities on the order of 0.1 g/cm. NFC loading drives the internal morphology of the comp...
متن کاملMicrofluidic setup for on-line SERS monitoring using laser induced nanoparticle spots as SERS active substrate
A microfluidic setup which enables on-line monitoring of residues of malachite green (MG) using surface-enhanced Raman scattering (SERS) is reported. The SERS active substrate was prepared via laser induced synthesis of silver or gold nanoparticles spot on the bottom of a 200 μm inner dimension glass capillary, by focusing the laser beam during a continuous flow of a mixture of silver nitrate o...
متن کاملLabel-free SERS detection of microRNA based on affinity for an unmodified silver nanorod array substrate.
A silver nanorod array has been used for the intrinsic SERS detection of microRNAs based on different binding affinities of ssRNA, thiolated ssDNA, and the RNA:DNA duplex, eliminating the need for a labelling step.
