| titleOfInvention | Degradable biomedical material with intrinsic fluorescence characteristic and preparation method thereof |
| abstract | The invention belongs to the technical field of biomedical materials, and discloses a degradable biomedical material with intrinsic fluorescence characteristic and a preparation method thereof. The structure of the degradable biomedical material with intrinsic fluorescence characteristic is shown as formula I, wherein R is HS-CH 2 ‑、HO‑CH 2 -, -H, n is an integer and n is not 0. The method comprises the following steps: heating citric acid and castor oil for reaction, then cooling, adding amino acid, continuing to heat for reaction, and performing subsequent treatment to obtain the degradable biomedical material with intrinsic fluorescence; the temperature of the heating reaction is 110-120 ℃; the temperature of the continuous heating reaction is 130-140 ℃. The medical material of the present invention is biodegradable, has excellent biocompatibility and has intrinsic fluorescence due to its unique cyclic structure; meanwhile, the medical material has high fluorescence intensity and good stability. |
