Nanotechnology has become enormously promising technology during last few decades and now it is estimated to have a significant effect on medical equipment. The possible effects of novel nanomedical applications on sickness identification, treatment, as well as anticipation are expected to improve healthiness care greatly. In addition, therapeutic selection may gradually be adapted to all patients' profile. Applications of nanomaterials are reported in operation, cancer diagnosis as well as therapy, biodetection of sickness markers, molecular imaging, implant technology, tissue engineering, as well as devices for drug, protein, and gene and radionuclide release. Various medical nanotechnology applications are at a standstill in their immaturity. A larger amount of nanodevices are presently under medical examination as well as several devices are commercially available. In this review work some applications of nanodevices in medical technology are also summarized.
