Effects of Magnetic Nanoparticle Drug Delivery Systems on Thrombosis and Neuroprotection in Brain Stroke Model

Nanomaterials refer to solid materials that are composed of ultrafine particles on the order of nanometers. Nanomaterials show broad application prospects in the fields of chemistry, metallurgy, electronics, aerospace, biology and medicine. The incidence of stroke in China ranks first in the world and the mortality rate is much higher than that in European and American countries. Drugs that are sensitive to the internal environment of the living body can be combined in the nuclear department to prevent them from reacting with the biological environment before reaching the target site, thereby reducing the efficacy or causing toxic side effects on other cells, tissues and organs. This project uses transgenic mice as experimental materials to establish an animal model of cerebral stroke. The light-embedded stroke model is used to simulate the pathological state of acute ischemic stroke. In vivo imaging and immunohistochemical techniques are used to analyze the administration of magnetic nanoparticles. Effects of the system on thrombolysis and neurological function protection in cerebral stroke models.
