Gold-silver nanoparticles instead of traditional diabetic drugs
Recently, we have published a pioneering work on green biosynthesis and complete characterization of gold and core shell silver-gold nanoparticles (AuNPs and Ag@AuNPs) via using green biopolymer in the influence of microwave radiation. These synthesized nanoparticles provide
Brownian motion of gold nanostructures made visible using SERS fluctuations due to single molecules
Surface-Enhanced Raman Spectroscopy (SERS) a surface-sensitive effect which produces a dramatic enhancement of the Raman signature of molecules adsorbed on some nanostructures such as gold nanoparticles. In practical terms, SERS allows the fast acquisition of spectral datasets
Recent advances in gold nanoparticle-based optic sensor
The ease in preparation and conjugation, stability, biocompatibility, as well as the size-dependent optical properties makes gold nanoparticles (Au NPs) one of the most popular nanomaterials for sensing of analytes of interest in the last decade. We
Enhanced absorption or transparency in hybrids of nanoparticles and graphene
The appealing side of nanotechnology lies in the fact that ordinary materials show surprising properties when their size is reduced to billionths of meters (nanometers). For example, we all know that silver is gray and gold is
Gold “bowtie” coming into reality on two-dimensional MoS2 surface
“Bowtie’’, which is a type of necktie, is very popular in our daily life. In some formal meetings or parties, bowtie is the normal choice to make you look good. Actually, this kind of bowtie structures of
