Etymology

Origin of biotechnology

First recorded in 1940–45; bio- + technology

Explanation

Biotechnology may sound like the stuff of science fiction, but it's a real area of science that deals with the overlap of engineering and biology. The Greek root bio- means "life," so biotechnology is "life technology" — technology that uses living things in products or processes, or that which focuses on designing things to benefit humans (living things) biologically. Vaccines, genetically modified foods, biofuels, and DNA fingerprinting are all examples of biotechnology. Ergonomics — designing equipment that reduces workers' discomfort, stress, or fatigue — is also often considered a branch of biotechnology, as it's technology developed to make our lives better from a biological perspective.
