A Revolution in Cellular Aging: A Narrative Review of the Promising Role of Nanorobots in Diagnosis, Treatment, and Regenerative Medicine

Nanorobots, also known as nanobots, are promising medical structures with significant potential for revolutionizing medical treatments and preventing their onset. Nanorobotics shows promise for diagnosing, treating, and regenerating age-related diseases. These tiny machines can repair cellular damage, deliver drugs, stimulate tissue regeneration, and monitor treatments. However, their application in controlling cellular aging is in its early stages, requiring more research to fully understand their potential and address safety concerns. Despite this, the benefits of nanorobots in age-related disease management justify further investigation. This narrative review article provides an overview of recent developments in nanorobotics, specifically focusing on its medical applications. PubMed and Google Scholar were utilized to conduct a comprehensive search using relevant keywords including "nanorobots", "cellular aging", "drug delivery systems", "cellular repair", "therapeutics", and "diagnosis". Only articles published between 2005-2023 were selected to support the arguments with up-to-date evidence. The extracted information includes nanorobot design, fabrication methods, applications, and key findings. A quality assessment was performed, and the data were categorized thematically to identify patterns and trends. The article concludes with an examination of the current state and future prospects of nanorobotics in different fields. Our research showed that nanorobots have significant potential in the diagnosis, treatment, and regenerative medicine of age-related diseases. They can detect and repair cellular damage caused by aging, targeting DNA damage and cellular protein misfolding. Nanorobots can also deliver drugs directly to affected areas, reducing side effects. Furthermore, they stimulate tissue regeneration and the growth of new blood vessels by delivering growth factors. Nanorobots can also monitor treatment effectiveness by measuring drug concentration in tumor cells. However, there are concerns about their safety in long-term use that require further research. Overall, nanorobots present an innovative approach to addressing cellular changes in aging, but more research is needed to understand their full potential and address safety concerns. The use of nanorobots in treating cellular aging has opened new possibilities in diagnosing and treating age-related diseases and it is a rapidly evolving field with the potential to revolutionize age-related disease treatment and improve the quality of life globally.
