However, the current synthesized fluorescent nanoparticles still have problems such as single function, poor stability and drug delivery efficiency. To solve these problems, this study aims to design multi-functional fluorescent nanoparticles, and realize the detection of multiple biological molecules, targeted recognition and multi-drug delivery through the combination of different materials, chemical compositions and surface modifications. This study will use metal, semiconductor, carbon-based materials as the main components, and use chemical synthesis and surface modification technologies to prepare fluorescent nanoparticles with various shapes, sizes, structures and fluorescence properties. The study will explore the biological
