Introduction

Gold nanoparticles labeled stretavidin can bind to trace antigens, antibodies and receptors, and has a wide range of applications in biological detection and biosensors. Biotin-linked streptavidin can be applied to nano-gold technology. The principle is that positively charged streptavidin is labeled with negatively charged gold nanorods-streptavidin and gold nanoparticles-streptavidin, and then tightly bound to biotin together. This allows the detection signal to be amplified on the basis of only nano-gold labels or only biotin labels.

Application

  • Gold nanoparticles labeled streptavidin can be used for the secondary detection of biotinylated probes in detection methods such as western blot, ELISA, light microscope and electron microscope.
  • Gold nanoparticles labeled stretavidin are increasingly used in biosensors. For example, stretavidin-coated gold nanoparticles are modified with biotinylated oligonucleotides, which can improve the sensitivity of nucleic acid tests.
  • A gold nanocluster immunoassay (GNCIA) was developed based on streptavidin-labeled fluorescent gold nanoclusters for early and sensitive detection of HIV infection.
