MicroRNAs (miRNAs) are small, non-coding RNA molecules that play a pivotal role in post-transcriptional gene regulation. Their dysregulation is implicated in a myriad of diseases, including cancer, cardiovascular disorders, and neurodegenerative conditions, making them attractive therapeutic targets or agents. However, the clinical translation of miRNA-based therapies faces significant hurdles, primarily due to poor stability, off-target effects, and inefficient cellular delivery. Nanoparticles (NPs) have emerged as a powerful platform to overcome these barriers. This review comprehensively examines the current landscape of nanocarriers—including lipid-based, polymeric, inorganic, and hybrid nanoparticles—for the safe and effective delivery of miRNA. We discuss the rational design of NPs for enhanced targeting, cellular uptake, and endosomal escape. Furthermore, we highlight recent preclinical and clinical advances in miRNA-nanoparticle therapeutics for oncology, cardiovascular diseases, and other pathologies. Finally, we address the ongoing challenges, biocompatibility concerns, regulatory landscape, and future perspectives in this rapidly evolving field, emphasizing innovations from the last five years.
