چکیده

A highly sensitive colorimetric metalloimmunoassay with a detection limit of 0.15 ng ml(-1) for human IgG based on copper-mediated etching of gold nanorods was proposed. The assay is more sensitive than traditional ELISA, electrochemical metalloimmunoassay and HRP mimic nanomaterial tag-based immunoassay.

Highly sensitive label-free colorimetric sensing of nitrite based on etching of gold nanorods.

A simple colorimetric method with high sensitivity and selectivity was developed for sensing of nitrite as low as 4.0 μM by naked eyes, which is based on etching of gold nanorods accompanied by shape changes in aspect ratios (length/width) and a visible color change from bluish green to red and then to colorless with the increase of nitrite.

Label-free colorimetric sensing of copper(II) ions based on accelerating decomposition of H2O2 using gold nanorods as an indicator.

A novel label-free colorimetric strategy was reported for sensitive detection of copper ions (Cu(2+)) by using the decelerating etching of gold nanorods (GNRs). H2O2 was employed as the oxidant for corrosion of GNRs, leading to the decrease of the aspect ratio of GNRs. In the absence of Cu(2+), the redox corrosion of GNRs by H2O2 occurred rapidly, causing the distinct color change of GNRs from ...

Enzymatic etching of gold nanorods by horseradish peroxidase and application to blood glucose detection.

Gold nanorods (AuNRs) have become some of the most used nanostructures for biosensing and imaging applications due to their plasmon-related optical response, which is highly sensitive toward minute changes in the AuNR aspect ratio. In this context, H2O2 has been used to trigger the chemical etching of AuNRs, thereby inducing a decrease of their aspect ratio. However, special conditions and rela...

Rapid-response and highly sensitive noncross-linking colorimetric nitrite sensor using 4-aminothiophenol modified gold nanorods.

A novel colorimetric nitrite ion sensor was developed utilizing 4-aminothiophenol (4-ATP) modified gold nanorods (GNR). In the presence of nitrite ions, the deamination reaction was induced by heating the 4-ATP modified GNR in ethanol solution, resulting in the reduction of the GNR surface charges, which led to aggregation of GNRs and a colorimetric response that was quantitatively correlated t...
