Nanomedicine is the medical application of Nanotechnology. Nanomedicine ranges from the medical applications of nanomaterials and biological devices, to nanoelectronics biosensors, and even possible future applications of molecular nanotechnology. Current problems for nanomedicine involve understanding the issues related to toxicity and environmental impact of nanoscale materials.
Functionalities can be added to nanomaterials by interfacing them with biological molecules or structures. The size of nanomaterials is similar to that of most biological molecules and structures; Therefore, nanomaterials can be useful for both in vivo and in vitro biomedical research and applications.
