Applications of nanotechnology in biomedicine

Nanobiotechnology is a new field in research, constituting the interface between the life sciences and nanotechnology. In this field, the size of the working range is between 1 nm and 100 nm. This new domain it proposes the exploitation of quality biomolecules and processes involved in the development of materials or devices with definite activity in medicine. Therapeutic nanotechnology seeks to provide specific features that can reduce morbidity and mortality in humans and animals, of which the most important are: a minimal invasive therapy, high density functions and the concentration in very small volumes. The first origins of the concept of nano-medicine are from Feynman's, who had the visionary idea of the nanorobots and similar mechanisms that could be designed, constructed, and placed in the body to perform cellular repairs at the molecular level. With the priorities crystallization in the medicine domain of XX and especially of the XXI’s century, also nanomedicine gained the momentum. In this respect the review proposes to introduce the reader to this fascinating field. There are provided information about cancer’s nanotherapy, examples of systems, applications of DNA, magnetic separation and manipulation of cells and biomolecules, nanotechnology applications in tissue engineering and many more. Also there are presented applications of nanotechnology in tissue engineering and about nano-robots.
