The future of nanocrystal-based drug delivery systems holds immense potential for revolutionizing pharmaceutical formulations, particularly in enhancing drug solubility, stability, and bioavailability. Continuous advancements in nanocrystal engineering are expected to enable more precise control over particle size, surface characteristics, and drug release kinetics, making them highly adaptable for diverse therapeutic applications. Hybrid nanocrystal systems integrating polymers, lipids, or inorganic materials are likely to emerge, offering synergistic benefits such as targeted delivery and extended circulation time. The evolution of surface modification techniques, including functionalization with ligands, peptides, or antibodies, will further enhance the specificity and efficacy of nanocrystals for precision medicine, particularly in oncology, neurodegenerative disorders, and infectious diseases.
