At present, Xianfeng Nano's available quantum dots are divided into graphene oxide quantum dots, graphene quantum dots, semiconductor quantum dots, etc. Customers can choose according to their experimental needs. The preparation methods of graphene quantum dots on sale are divided into bottom-up and top-down, with different colors of luminescence available, such as green light, blue light, red light, and white light. Meanwhile, graphene quantum dots with different functional groups can be selected, which is also helpful for later modification coupling. In addition, nitrogen doped and boron doped graphene quantum dots can be selected. At present, the applications of graphene quantum dots are mostly focused on fluorescence imaging, nanoadditives, antibacterial, and biotoxicity.\u003c\/span\u003e\u003c\/sup\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003csup\u003e\u003cspan\u003e\u003cstrong\u003eTechnical Parameter\u003c\/strong\u003e\u003c\/span\u003e\u003c\/sup\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003csup\u003e\u003cspan\u003eForm: Light yellow particles\u003c\/span\u003e\u003c\/sup\u003e\u003c\/p\u003e\n\u003cp\u003e\u003csup\u003e\u003cspan\u003ePurity:~80%\u003c\/span\u003e\u003c\/sup\u003e\u003c\/p\u003e\n\u003cp\u003e\u003csup\u003e\u003cspan\u003eNote: The water solubility and fluorescence intensity of the powder sample are slightly lower than those of the corresponding solution.
