Abstract
Intelligent drug delivery systems, as a significant research direction in modern biomedicine, aim to enhance therapeutic effects and reduce side effects by precisely controlling the drug release process. This study leverages the latest advancements in nanotechnology and biomaterials to develop a novel intelligent drug delivery platform. The core of this platform lies in using environment-responsive polymers and targeted molecules for specific recognition of lesion sites and controlled drug release. First, multifunctional nano-carriers with pH, temperature, or redox sensitivity were designed and synthesized, and their stability and response performance under simulated physiological conditions were verified through in vitro experiments. Subsequently, the system's in vivo distribution, pharmacokinetic characteristics, and therapeutic effects were evaluated using animal models. The results showed that the system can significantly increase drug accumulation in tumor tissues while reducing toxicity to normal tissues. Additionally, this study explored the potential applications of the platform in various disease treatments, including cancer, inflammation, and infectious diseases, further demonstrating its broad applicability.
