Abstract
Mesoporous silica nanoparticles (MSNs) have emerged as cornerstone biomaterials for nanomedicine due to their highly tunable physicochemical properties. This review highlights recent breakthroughs in MSN-based platforms for disease theranostics. We systematically outline fundamental synthesis strategies and detail how surface functionalization-imparting properties such as targeting, stimuli-responsiveness, and biomimicry-transforms MSNs from passive carriers into intelligent theranostic agents. The review then summarizes the major contributions of these engineered platforms across key diagnostic ( e.g. , advanced imaging) and therapeutic ( e.g. , targeted drug delivery, dynamic therapies) applications, underscoring their potential in tackling complex diseases. Finally, we address the critical challenges hindering clinical translation, including manufacturing scalability and long-term biocompatibility. We conclude by outlining future directions, such as integration with emerging modalities like immunotherapy, aimed at accelerating the bench-to-bedside transition of MSN-based nanomedicines.
