Intelligently thermoresponsive flower-like hollow nano-ruthenium system for sustained release of nerve growth factor to inhibit hyperphosphorylation of tau and neuronal damage for the treatment of Alzheimer's disease.Alzheimer's disease (AD) seriously affects human health and life and lacks effective treatments.  Due to its excellent photothermal effect, under the near-infrared (NIR) irradiation, the nanocomposite could effectively penetrate the blood-brain barrier (BBB) and respond to phase changes in the lesion area, releasing NGF, which inhibited tau hyperphosphorylation, reduced oxidative stress, and more importantly restored nerve damage and maintained neuronal morphology, thereby significantly improving learning and memory in AD mice.
