Nanotechnology & Nanoparticles and Their Advances of Investigation and Application in the Fields of Biomedicine

Nanotechnology is a technology for studying the movement and characteristics of electrons, atoms and molecules in a space of 1-100 nm and for manufacturing products with specific functions.Nanotechnology is penetrating deeper and deeper into the field of biomedicine. Nanoparticles have quantum size effects, surface effects, small size effects and macroscopic quantities. Subtunnel effect makes it exhibit many unique properties, such as large specific surface area, many surface active centers, high surface reactivity, strong adsorption capacity and high catalytic capacity. The understanding of particle characteristics opens up a new way for the application of biomedical research to further development and provides a more scientific means.
