Abstract
The world is entering an era of strong infectious diseases, and it is urgent to develop a new type of rapid, efficient detection system. This graph specifically illustrates the detection function of the gold nanoparticles, and the gold nanoparticles-based sensor. Gold-based nanoclusters (NCs) which has a small particle size, has a high degree of stability and no impact on the biological activity. Gold-based NCs has a surface plasma resonance effect and produces visible color, which can be detected by observing the color change using the agglomeration reaction of the detected substance with Gold-based NCs. In order to specifically detect certain biomolecules, some functional groups or small DNA molecular chains of nanolodin are usually modified on it to have a selective detection capability. In the review, we introduce a total of four nano-gold applications, for bacteria, viruses, DNA and cancer, also, respectively elaborating some recent Gold-based NCs detection applications.
