Use of Biotechnology in Forensics

Mike Cortes

What is biotechnology and how is it used in forensics?

Biotechnology is any technology pertaining to or involving the physical aspects of any organism. In forensics, this can involve testing bodily fluid samples, skin samples, DNA processing, and quite a few others

How is it being used currently?

Forensic scientists use biotechnology techniques to help detect important evidence. For example, a chemical called luminol, which glows brightly in the presence of blood, is used to detect small amounts of blood that are not visible to the naked eye. They can then analyze the DNA in this or other bodily fluids to identify a person.

Benefits and Disadvantages

Biotechnology makes allows a crime inspector to accurately identify a suspect or victim. It's great to save time and effort in tracking down clues and makes great TV.

Unfortunately, it also is very expensive, budgeting millions of dollars from the government.


Forensic science has affected humanity by requiring all adults and felons to undergo blood work and fingerprinting. This is so that i the event of a crime or missing person evidence can processed faster.

Economically, it has drained millions of dollars in government funding which could be used on other things.

Being as the use of biotechnology is such an efficient form of crime investigation, it has been used by numerous police agencies in countries around the world.

In the future, forensic science will become more often used with the development of new biotechnology. As time goes on, less and less physical evidence will be required for a person to be identified. It will also most likely require people to give more DNA evidence more frequently, earlier in their life. Who knows, at some point even babies could have their genetic markers mapped the day they're born.
