Seed‐mediated Growth of Gold inside Hollow Silica Nanospheres for Sensing Peroxide and Glucose Concentrations

Abstract

A growth spurt: Catalytic growth of Au NPs inside a cavity protected by hollow silica nanoshells, which is accompanied by an SPR spectroscopic enhancement, allows for the quantitative detection of H2O2 and glucose concentrations, even in the presence of interfering BSA proteins.

Strategies for enhancing the sensitivity of plasmonic nanosensors

“…Because the reducing agent may reduce gold or silver ions, biocatalyzed reactions can be directly used for the enlargement of AuNPs [251][252][253][254]. Unlike scanometric detection, in the scheme of biocatalytic enlargement of AuNP, an analyte acts as a reducing agent leading to the enlargement of AuNPs.…”

“…Recently, Ha and co-workers developed a glucose sensor that can be used in a highly interfering matrix using a porous silica nanoshell (Fig. 21) [253]. The presence of a hollow nanostructure favours the penetration of small molecules but blocks large biomolecules such as DNA and proteins.…”

Retraction: Nanoporous PdCu Near‐Surface Alloy for Nonenzymatic Glucose Biosensing

“…So far, many approaches have been developed for glucose detection, such as optical approaches, electrochemiluminescene, colorimetry, electrochemical approaches, etc. [4,5] Of these, the electrochemical approach has attracted much attention owing to its simplicity, high sensitivity, low cost, and compatibility towards miniaturization.…”
