Biotech, the preferred shorthand for biotechnology, is a field of technology focused on the use of biology. The main focus of this field is the use of cellular and biomolecular processes to develop new products. While the modern use of the term focuses on medical research done in labs, biotechnology is considerably more expansive than most people realize. The three primary fields of focus are food, fuel, and medicine. For example, bread and cheese come from ancient biotechnology techniques. Whether your job as a biotechnologist focuses on developing a drug for a company or trying to generate electricity from plants, biotechnology has the potential to create significant advances in technology, and that's why so many universities and companies study it.
