Dynamic light scattering(DLS),as a conventional analysis method by particle size,has the advantages of free separation,easy operation,low test costs and easy data processing etc.Functionalized AuNPs,in addition to thier own particle properties,could also specifically identify the target,significantly amplify the light scattering signals from the target,and ultimately achieve a fast,specific and sensitive detection on the target through the DLS technique.In this paper,research progresses on the application of DLS with gold nanoparticles in detection on the target were reviewed.Some problems in the application process of DLS technique were discussed,which was intended to provide some reference for its practical application.
