热沉淀法制备IOMNPs,PEG-PGA修饰IOMNPs 形成PEG-PGA-IOMNPs,明胶和IOMNPs采用乳化-溶剂蒸发法得到GIMs。三者充分干燥后TEM观察形貌。
IOMNPs were prepared by thermal precipitation method, and PEG-PGA modified IOMNPs to form PEG-PGA-IOMNPs. GIMS was obtained by emulsification and solvent evaporation of gelatin and IOMNPs.The morphologies of the three were observed by TEM after full drying.
