Ferulic acid-loaded fluorescent chitosan nanoplatform for Al3+/FA sensing and bioactivity against endometrial cancer
摘要
Endometrial cancer remains a major health concern, underscoring the need for advanced diagnostic and therapeutic strategies. In this study, a multifunctional chitosan-based fluorescent nanoplatform (CS-1@FA) was rationally designed by functionalizing chitosan with a plant-derived modifier (Compound 1) and subsequently loading ferulic acid (FA). Unlike conventional chitosan- or FA-based nanosystems, CS-1@FA integrates intrinsic fluorescence, ratiometric metal-ion sensing, and enhanced bioactivity within a single platform. The resulting nanocomposite exhibited stable photoluminescence with excellent pH and thermal stability, enabling sensitive and selective fluorescence and ratiometric detection of FA and Al3+ ions. Furthermore, cell viability assays demonstrated good biocompatibility and a markedly enhanced inhibitory effect of FA-loaded nanoparticles on endometrial cancer cells compared with free FA. Overall, these findings highlight CS-1@FA as a versatile fluorescent nanoplatform that combines fluorescence sensing capability with biological activity, offering a promising material strategy for disease-related metal ion detection and nanomedicine-oriented applications.
