Biological Engineering is the combination of concepts of Biology with the principles of Engineering to create economically feasible products. It is used in the design of medical devices, biocompatible materials, diagnostic equipment, renewable bioenergy and other areas to make living standards better.
In general, Biological Engineers strive to either imitate the biological systems to create products or modify and control biological systems so that they can replace, enlarge, sustain, or anticipate chemical and mechanical processes.
