Introduction
Biotech engineering, also known as biotechnology engineering, is an interdisciplinary field that merges principles of biology, chemistry, genetics, and engineering to develop innovative solutions for various applications.
It harnesses living organisms' cellular and molecular processes to create valuable products and technologies that benefit diverse industries, including medicine, agriculture, the environment, and more. The growing popularity of this field has led to a large number of applications at biomedical science colleges.
Historical Development of Biotech Engineering
Biotech engineering has a rich history that dates back to ancient times when humans first harnessed microorganisms for food fermentation and brewing. However, it wasn't until the late 20th century that the term "biotechnology" emerged, with the successful birth of the first genetically engineered human insulin in 1978. This groundbreaking achievement paved the way for further research and applications in the field of biotechnology.
In the 1970s, the discovery of recombinant DNA technology revolutionized biotech engineering by allowing for the manipulation and modification of genetic material. This breakthrough opened up new possibilities for scientific advancement. Since then, the field has seen rapid advances, including gene editing techniques like CRISPR-Cas9, synthetic biology, and personalized medicine.
