Nanotechnology refers to the design, manipulation, and application of materials at the nanoscale level, typically between 1 and 100 nanometers. At this scale, materials exhibit unique physical, chemical, and biological properties that differ significantly from their bulk counterparts.

The integration of nanotechnology into healthcare has given rise to the field of nanomedicine, which encompasses the use of nanoscale materials and devices for disease diagnosis, prevention, monitoring, and treatment.

Traditional therapeutic approaches often face challenges such as poor drug bioavailability, systemic toxicity, limited targeting capability, and inadequate diagnostic sensitivity. Nanotechnology addresses many of these limitations by enabling targeted drug delivery, improved imaging resolution, and enhanced therapeutic precision.

Over the past two decades, numerous nanoparticle-based products have been developed for clinical use, particularly in oncology, infectious diseases, cardiovascular medicine, and tissue engineering.

This study examines the applications of nanotechnology in medical practice and evaluates its current and future role in healthcare.
