Nanomedicine and nanotechnology represent one of the most transformative frontiers in modern science, redefining how diseases are diagnosed, treated, and prevented at the molecular and cellular levels. By operating at the nanoscale —typically between 1 and 100 nanometers—these technologies enable unprecedented precision in interacting with biological systems, far beyond the capabilities of conventional medical approaches. At this scale, materials and devices exhibit unique physical, chemical, and biological properties that can be harnessed to improve therapeutic efficacy , reduce systemic side effects, and target disease mechanisms with extraordinary accuracy. Nanomedicine integrates principles from physics, chemistry, biology, engineering, and artificial intelligence , positioning itself as a cornerstone of next-generation healthcare. From targeted drug delivery systems and intelligent nanorobots to nanoscale biosensors and regenerative therapies , advances in nanotech...
