The isoquinoline alkaloid berberine, a bioactive compound derived from various plants, has demonstrated extensive therapeutic potential. However, its clinical application is hindered by poor water solubility, low bioavailability, rapid metabolism, and insufficient targeting. Metal-based nanoplatforms offer promising solutions, enhancing drug stability, controlled release, and targeted delivery. This review comprehensively explores the synthesis, physicochemical properties, and biomedical applications of metal-based nanocarriers, including gold, silver, iron oxide, zinc oxide, selenium, and magnetic nanoparticles, for berberine delivery to improve berberine's therapeutic efficacy. Recent advancements in metal-based nanocarrier systems have significantly improved berberine delivery by enhancing cellular uptake, extending circulation time, and enabling site-specific targeting. However, metal-based nanoplatforms encounter several limitations of potential toxicity, limited large-scale productions, and regulatory constraints. Addressing these limitations necessitates extensive studies on biocompatibility, long-term safety, and clinical translation. By summarizing the latest innovations and clinical perspectives, this review aims to guide future research toward optimizing berberine-based nanomedicine for improved therapeutic efficacy.
