Embodiment 1
[0035] In this embodiment, the fluorescence-enhanced two-color visualized drug detection probe is prepared according to the following steps:
[0036] (1) Synthesis of polydopamine nanospheres
[0037] Add 0.1g of dopamine hydrochloride to a mixed solution of 60mL Tris buffer and 40mL isopropanol, and stir for 48 hours; after the reaction is completed, centrifuge, wash with ultrapure water for 3-5 times, and dry in a vacuum oven at 30°C for storage. That is, polydopamine nanosphere powder is obtained; in the mixed solution, the concentration of Tris buffer is 10 mM.
[0038] The absorption spectrum of gained polydopamine nanosphere powder is as follows figure 1 shown.
[0039] (2) Synthesis of copper nanoclusters
[0040]Synthesis of copper nanoclusters emitting orange fluorescence: Mix 360mmol copper nitrate and 9mol glutathione in 8mL ultrapure water, adjust the pH to 4 with 1.5M sodium hydroxide to obtain a mixed solution; The volume ratio of the solvent is 1:60, ethanol...
