Target Analyte

A simple and rapid positive–negative colorimetric approach to determine the presence of antimony ions based on the use of gold nanoparticles conjugated with oligonucleotide (poly-A sequence) is developed. Colorimetric measurements reveal that the aggregates of modified gold nanoparticles were afforded after adding antimony ions, thus changing the solution color from pink to blue. The results of aptamer’s interaction on the gold nanoparticle surface with the target analyte can be detected either by photometry or by the naked eye. The realized assay provides rapid (2 min), sensitive (detection limit 10 ng/mL), specific, and precise (variation coefficient less than 3.8%) detection of antimony (III) in drinking water.

Rabbit Polyclonal Antibody

We have successfully developed gold nanoparticle based immunostrip assay to detect protein-A (PA). Rabbit polyclonal antibody IGg (αPA) that has affinity to PA was conjugated to gold nanoparticles (GNPs) and the gold nanoconjugate (αPA-GNP) was used to detect protein-A by simple immunostrip assay method. ELISA experiments were used to confirm the retention of binding affinity of antibody towards protein-A after conjugation with gold nanoparticles.
