| titleOfInvention | Quantum dot fluorescent microsphere and preparation method thereof |
| abstract | The invention relates to a quantum dot fluorescent microsphere and a preparation method thereof. The preparation method comprises the following steps: preparing the water-phase quantum dots with the surface modified with active groups by a method of ligand exchange or coating an amphiphilic polymer or a method of direct synthesis in a water phase; activating the microspheres to obtain active microspheres with groups reacting with active groups on the surfaces of the active quantum dots; carrying out covalent bonding reaction on the water-phase quantum dots with the surface modified with active groups and the active microspheres to obtain the quantum dot fluorescent microspheres; wherein the active microspheres have groups that react with the active groups. According to the preparation method, the active groups and the active microspheres are subjected to covalent bonding reaction, so that the connection stability between the quantum dots and the microspheres is greatly improved, the fluorescence intensity and the stability of the fluorescence intensity are improved, and the requirement of detection is met for a long time. |
