Medical Use of Nanoparticles: Drug Delivery and Diagnosis Diseases

Researchers today are able to encapsulate medicine in nanoparticles, the size of viruses. The nanoparticles are effective for drug delivery—the delivery of the medicine to the body—because they can very precisely find diseased cells and carry the medicine to them. This means that one can suffice with less dosage and thereby fewer side effects. In addition, nanoscience and nanotechnological methods are spurring the development of more sophisticated tools for detecting diseases, such as cancer and atherosclerosis, at early stages and performing neurosurgery. Applications of nanotechnology in disease diagnoses are developing rapidly. Their unique size-dependent properties make these materials superior and indispensable in many areas of human activity.
