Organ-specific Applications of Nanomedicine a Review of Targeted Delivery Systems in Major Human Organs
Year: 2025
Type: article
Abstract: Nanomedicine represents an innovative therapeutic strategy, offering targeted drug delivery with greater efficacy and reduced systemic toxicity. In this review we investigate organ-specific applications of nanomedicine; specifically targeting delivery systems designed for major human organs including heart, lung, brain, liver kidney and digestive tract. Each organ presents distinct anatomical and physiological barriers which must be navigated using specific nanoparticle (NP) systems designed for each one. Organic nanoparticles like liposomes, dendrimers and polymeric micelles offer superior biocompatibility and flexibility when it comes to drug delivery and functionalization. Meanwhile inorganic nanoparticles like gold, silver and mesoporous silica possess highly adjustable physical and chemical properties useful in diagnosis as well as therapy applications. Hybrid nanoparticles which combine organic with inorganic components have become promising platforms due to their multifunctionality and structural versatility for use as theranostic platforms. Organ-targeted nanomedicine has enjoyed significant preclinical success. Cardiac-targeting nanoparticles aid myocardial repair post-infarction; brain-targeted systems deliver drugs across the blood-brain barrier; while kidney-targeted nanomedicine may treat glomerular or fibrotic diseases. Yet several challenges still persist regarding long-term biocompatibility, off-target toxicity concerns, regulatory uncertainties etc.This review highlights recent advancements in organ-specific nanomedicine, targeting mechanisms and therapeutic implications. Further improvements in nanoparticle design, targeting strategies, safety evaluation and application to clinical therapies is vital to making them truly useful therapies.
