High-sensitivity SERS based sensing on the labeling side of glass slides using low branched gold nanoparticles prepared with surfactant-free synthesis

Abstract

High-sensitivity dopamine detection on aggregated low branched nanoparticles on labelling side of glass slide as a SERS based sensor.

A novel lateral flow immunochromatographic assay using a recombinant VP2 antigen for total antibody detection of canine parvovirus-2

“…These results show good agreement with previous studies on the characterization of gold nanoparticles. 23 The verication of citrate capping ligand replacement with protein on the AuNP surface was conducted using UV-vis spectrophotometry. In an earlier investigation, Kozlowski and colleagues noted that the substitution of citrate with protein on gold nanoparticles results in a redshi of the SPR band, which is attributed to alterations in the surface molecules' dielectric constant.…”

General Background of SERS Sensing and Perspectives on Polymer‐Supported Plasmon‐Active Multiscale and Hierarchical Sensor Particles

“…[ 7,57 ] In addition to the silicon wafers, various glass‐based solid supports can also be used for depositing metal nanostructures on the surface. [ 61 ] To achieve a high binding reproducibility, the surface of base materials and metal colloids can be functionalized with various ligands which possess functional groups such as amine, thiol, and cyanide ( Figure A). [ 62 ] On the other hand, a wide range of lithographic techniques (top‐down approaches) such as soft lithography, photolithography, electron beam lithography, etc., can able to form ordered arrays of the nanoparticles on the solid base.…”

Polyacrylamide Gel Scaffold Immobilized with Silver Nanoparticles as SERS Substrates and Catalysts for H2 Generation via Methanolysis of NaBH4

“…Depending on the designated applications, an array of materials can serve as a support. The choices include glass/quartz, minerals, silica, zeolites, papers, carbonaceous substances, and polymers, among which polymer materials , are the most amenable to property diversification. With the enlarged surface area on these supports, which is generally one of the most sought properties of the support, the deposition of AgNPs is usually done by exposing the support materials to a dispersion of separately prepared AgNPs.…”
