: Organelle-specific targeted drug delivery has emerged as a promising approach in the field of drug delivery and therapeutics. This innovative strategy involves the precise delivery of therapeutic agents to specific organelles within cells, such as the nucleus, mitochondria, endoplasmic reticulum, or lysosomes, with the aim of enhancing drug efficacy while minimizing offtarget effects. Despite its tremendous potential, organelle-specific drug delivery faces several key challenges. One major challenge is the development of delivery systems that can accurately navigate the complex intracellular environment and deliver drugs exclusively to the desired organelles. Achieving this level of precision demands advanced nanotechnology and biomaterials engineering. Furthermore, ensuring the safety and biocompatibility of these delivery systems is paramount. Recent advancements in this field include the development of nanocarriers, such as liposomes, nanoparticles, and dendrimers, designed to target specific organelles through ligandreceptor interactions or pH-responsive mechanisms. Additionally, advancements in molecular biology and genetic engineering have enabled the design of genetically encoded organellespecific drug delivery systems. The therapeutic implications of organelle-specific drug delivery are vast. This approach has the potential to revolutionize the treatment of diseases with organelle- specific pathologies, such as neurodegenerative disorders, cancer, and mitochondrial diseases. By precisely targeting the organelles involved in disease progression, the efficacy of therapies can be significantly improved while minimizing collateral damage to healthy tissues.
