Smart Delivery Systems Based on Poly(glycidyl methacrylate)s-Coated Organic/Inorganic Core-Shell Nanohybrids.

Abstract

Smart delivery systems have gained momentum over the last few decades due to their potential to realize enhanced therapeutic efficacy. Poly(glycidyl methacrylate)s (PGMAs), which spring up like mushrooms, have drawn great attention in the theranostics field, especially in multifunctional theranostic systems. The marriage of PGMAs with functional inorganic cores is expected to integrate diagnosis (e.g., fluorescence, X-ray computed tomography, magnetic resonance, photoacoustic and upconversion luminescence imaging), treatment, or multimodal synergistic therapies (e.g., chemotherapy, gene therapy, photothermal therapy) in one pot for personalized medicine. In this review, recent progress in various PGMA-coated nanohybrids based on the type of integrated inorganic nanoparticle, including silica nanoparticles, magnetic nanoparticles, quantum dots, gold nanoparticles, gold nanorods, metal-organic frameworks, cellulose nanocrystals, and their core-shell nanostructures is systematically reviewed. Future work in this field is anticipated to be devoted to developing efficient real-time-imaging-guided multimodal synergistic therapies.
