| titleOfInvention |
A kind of ferric oxide bismuth sulfide nanocomposite material and its preparation and application |
| abstract |
The invention discloses a ferric oxide/bismuth sulfide nanocomposite material and its preparation. The preparation method is as follows: dispersing Fe 3 O 4 and dopamine into a Tris-HCl buffer solution to obtain Fe 3 O 4 @PDA nanoparticles; dispersing the bismuth source in a solvent, and then adding dropwise to a bovine serum albumin solution to obtain BSA ‑Bi 2 S 3 particles; Fe 3 O 4 @PDA nanoparticles were dispersed into Na 2 HPO 4 ‑NaH 2 PO 4 buffer solution, and BSA‑Bi 2 S 3 particles were added to obtain Fe 3 O 4 @PDA@BSA‑ Bi 2 S 3 nanoparticles. The product obtained by the invention is easy to prepare and non-toxic, and has good biocompatibility, colloid stability and MRI&CT contrast effect at the level of cells and animals. |
