Additive manufacturing in nano drug delivery systems

The adoption of innovative mixing and fabrication technologies in the pharmaceutical industry has inspired research on nano-drugs and expanded the scope of study in the field. Researchers' interest in the recently discovered drug delivery nanoparticles has increased significantly. This interest is especially seen in the specific preparation of nanoparticles as drug carriers through the use of three-dimensional (3D) printing, a modern additive manufacturing (AM) technology. The benefits of 3D printing, especially at the nanoscale, make it an innovative technology that could revolutionize the pharmaceutical and regenerative medicine industries. The laborious creation of intricate structures made possible by nanoscale 3D printing brings up the possibility of developing nanomedicine and producing functioning tissues and organs. The uses of AM in nano drug delivery systems (NDDS) are highlighted in this study, with a focus on how it can improve drug release kinetics, enhance therapeutic efficacy, and minimize side effects. A new era of personalized medicine has begun with the development of patient-specific formulations made possible by the customization capabilities of 3D printing. This review discusses the various uses of AM in NDDS while addressing issues including scalability, biocompatibility, and regulatory concerns. This review highlights the developing integration between AM and nanotechnology in medicine delivery and discusses ongoing research activities and possible solutions. As this innovative technology develops further, it has the potential to completely change the pharmaceutical development field by providing fresh approaches to the complex problems of contemporary healthcare and advancing the ideas behind drug delivery.
