Biotechnology is a broad interdisciplinary field that applies biological systems, living organisms, or components of them to develop or enhance materials and processes. This scientific area encompasses techniques ranging from molecular biology to synthetic biology, utilizing these mechanisms for various industrial, medical, and agricultural purposes. Methods include genetic engineering, enzyme purification, and the large-scale fermentation of useful compounds. Applications are diverse, covering the development of diagnostic tools, the synthesis of novel chemicals, the production of biofuels, and the creation of biomaterials. The field is fundamentally focused on manipulating biological information and natural processes to solve complex technical challenges.
