The present invention relates to a pH-responsive metal-catechol derivative nanoparticle for drug delivery based on a mussel adhesive protein, particularly Fe(III)-DOPA nanoparticle, and a method for preparing the same. A nanoparticle for drug delivery according to the present invention is prepared using a pH responsive substance, catechol derivative-metal complex, particularly Fe(III)-DOPA complex, based on a mussel adhesive protein. Thereby, the present invention has excellent biocompatibility, is capable of easily and quickly penetrating into a target cell, and releases a loaded drug under acidic conditions, which enables to selectively deliver a drug to a specific disease having an acidic environment.
本发明涉及一种基于贻贝黏附蛋白的pH响应性金属-邻苯二酚衍生物纳米颗粒用于药物传递,特别是Fe(III)-DOPA纳米颗粒,以及其制备方法。本发明的药物传递纳米颗粒使用pH响应性物质,邻苯二酚衍生物-金属配合物,特别是基于贻贝黏附蛋白的Fe(III)-DOPA配合物制备而成。因此,本发明具有优异的生物相容性,能够轻松快速地渗透进入目标细胞,并在酸性条件下释放所载药物,从而能够选择性地将药物传递到具有酸性环境的特定疾病。
