Microfabrication in biology and medicine.

Microfabrication uses integrated-circuit manufacturing technology supplemented by its own processes to create objects with dimensions in the range of micrometers to millimeters. These objects can have miniature moving parts, stationary structures, or both. Microfabrication has been used for many applications in biology and medicine. These applications fall into four domains: tools for molecular biology and biochemistry, tools for cell biology, medical devices, and biosensors. Microfabricated device structures may provide significantly enhanced function with respect to a conventional device. Sometimes microfabrication can enable devices with novel capabilities. These enhancing and enabling qualities are conferred when microfabrication is used appropriately to address the right types of problems. Herein, we describe microfabrication technology and its application to biology and medicine. We detail several classes of advantages conferred by microfabrication and how these advantages have been used to date.
