Nanotechnology applied to biology requires a thorough understanding of how molecules, sub-cellular entities, cells, tissues, and organs function and how they are structured. The merging of nanomaterials and life science into hybrids of controlled organization and function is possible, assuming that biology is nanostructured, and therefore man-made nano-materials can structurally mimic nature and complement each other. By taking advantage of their special properties, nanomaterials can stimulate, respond to and interact with target cells and tissues in controlled ways to induce desired physiological responses with a minimum of undesirable effects. To fulfill this goal the fabrication of nano-engineered materials and devices has to consider the design of natural systems. Thus, engineered micro-nano-featured systems can be applied to biology and biomedicine to enable new functionalities and new devices. These include, among others, nanostructured implants providing many advantages over existing, conventional ones, nanodevices for cell manipulation, and nanosensors that would provide reliable information on biological processes and functions. |
