Abstract

Stroke is one of the most serious problems that seriously affect people's health and brings huge economic burden to society. The development of new nanocarriers with desired degradability and targeted ability is of great significance for efficient drug delivery. In recent years, nano drug delivery system has developed rapidly and applied to treat ischemic stroke. Here, we report the synthesis and functionalization of monodisperse hollow structured MnO2 (H-MnO2). The highly monodisperse H-MnO2 with uniform morphology was obtained by in situ growing MnO2 on solid silica nanoparticles and subsequently removing the silica core. After successive modification of poly ethylene glycol(PEG), we further verified their protective effect on ischemic stroke in our study.
