Nanoparticle-hydrogel composites for precision medicine

Nanoparticle-hydrogel composites hold significant potential for precision medicine. They effectively combine the molecular programming capabilities of nanoparticles and the macroscopic spatial management properties of hydrogels. This review examines the material composition of nanoparticles and hydrogels, the methods used to create composite structures, and the design elements that facilitate therapeutic customization. In theory, these systems can be engineered to target patient-specific biomarkers and coordinate multi-agent release with disease progression while adapting therapeutic dosing to individual treatment contexts that are critical for precision medicine applications. Through analysis of recent advances in cancer immunotherapy, drug delivery, gene therapy, tissue engineering, and personalized vaccination, we emphasize that clinical success demands equal focus on mechanistic sophistication along with practical considerations including manufacturing reproducibility, standardized material characterization, and evaluation frameworks that assess clinically relevant outcomes beyond traditional laboratory metrics. This review discusses the key approaches to strategically design nanoparticle-hydrogel composites to bridge the gap between preclinical studies and clinical translation in precision medicine.
