| titleOfInvention | Preparation method of bamboo charcoal/chitosan composite microspheres with drug slow release performance |
| abstract | The invention belongs to the technical field of composite microspheres, and discloses a preparation method of bamboo charcoal/chitosan composite microspheres with drug slow release performance, which comprises the following steps: fully dissolving chitosan into 1.0 volume percent of acetic acid solution at 40-60 ℃, then sequentially adding bamboo charcoal powder and the medicinal solution, and fully stirring until the mixture is uniformly mixed; obtaining a viscous, flowable mixture; dripping the mixed solution of bamboo charcoal powder/chitosan/drug into prepared polyphosphate solution under the condition of heat preservation to obtain microspheres, carrying out crosslinking formation for a certain time, filtering, cleaning residual polyphosphate on the surface, washing with ethanol, and drying at normal temperature to obtain the drug-loaded microspheres. |
