It is a vast field of biology that involves the use of biological systems and creatures in the development and production of goods. It often overlaps with allied scientific subjects, depending on the tools and applications used. As a result of the advancements in science and technology in the late twentieth and early twenty-first centuries, biotechnology has expanded to encompass a wide range of disciplines, including genomics, recombinant gene techniques, applied immunology, and the development of pharmaceutical treatments and diagnostic tests. It was Karl Ereky in 1919 who coined the word "biotechnology," which refers to the creation of goods from raw materials with the assistance of living organisms, as opposed to the usage of machines.
