The present state of medication formulations using nanotechnology has made it possible to address and treat difficult disorders. Although they vary in size, nanoparticles typically have a size between 100 and 500 nm. It is possible to develop complex techniques that encapsulate pharmaceutical and imaging substances while maintaining their stealth qualities by varying the size, surface characteristics, and composition of the nanoparticles. These gadgets might additionally deliver medications to specific areas and provide controlled release therapy. Patients take fewer doses of the drug when it is delivered in a targeted and sustained way, which also lessens the toxicity of the treatment. Nanotechnology has demonstrated potential in the management of several illnesses, such as cancer and AIDS, among many others. Advanced diagnostic tests are also included. The benefits and drawbacks of employing nano medicines to transfer medications from synthetic or natural sources to therapeutic settings are also covered. Additionally, we have included information about current trends and viewpoints in the field area of Nano medicine.
