Research Progress of Functional Materials in Drug Degradation, Adsorption and Integrated Diagnosis and Treatment

With the deep integration of pharmacy and materials science, functional materials are increasingly applied in drug development, environmental remediation of pharmaceutical pollutants, and clinical diagnosis and treatment. This article focuses on multiple application scenarios of functional materials, including drug degradation, drug adsorption, drug analysis and detection, electrochemical detection, and bioimaging. It systematically reviews the structural characteristics, modification strategies, and latest research progress of typical functional materials such as metal–organic framework materials, nanocomposites and bio-based materials in various application fields. The article also analyzes key challenges faced by functional materials in multi-scenario applications, such as biocompatibility, stability, and large-scale preparation. In light of the trends in precision medicine, it outlines future directions for the application of functional materials in the field of pharmacy, aiming to provide references for the design and development of multifunctional materials and innovative applications in pharmaceuticals.
