ZnS nanoparticles, as an important semiconductor nanoparticle, have high quantum yield and long life, and therefore have good fluorescent properties. This study aims to improve its fluorescent properties by doping different atoms (Cu, Ag, Au, Cd, etc.) to achieve controlled modification of ZnS. At the same time, using the phenomenon of plasmonic resonance to enhance its fluorescence intensity and stability. Different biological functionalization methods are used to enable them to combine with biological molecules (such as proteins, DNA, etc.) to achieve biological imaging and drug carrier functions.Keywords: ZnS nanoparticles, doping, plasmonic fluorescence enhancement, biological functionalization modification, biological imaging
