In this post we will learn about forensic science and forensic drug chemistry. Also learn about fathers of various fields of forensic science and famous forensic scientists and forensic chemist.

Definition of Forensic Science

Forensic science is the application of scientific methods and techniques to matters under investigation by a court of law. Almost all branches of science may contributes to solve a crime scene, hence comes under forensic science.


Forensic Drug Chemistry

Forensic drug chemistry is the sub-branch of chemistry.  Forensic drug chemistry is used in identification of matter generally illegal drugs. The Forensic chemist examines the samples bring in forensic chemistry lab. Forensic chemist tries to find the name of matter or drug by examining the atoms and molecules in matter. Also find how these atoms and molecules interact and bond with each other. As we know, all matter or drug substance has a chemical signature (Spectrum, that you study under spectroscopy) and or some physical and chemical properties which are unique to only that substance. Forensic chemists use these physical and chemical properties to identify matter or drug substances using scientific techniques or methods. Findings by examining samples are presented as facts in court. Forensic chemistry covers analysis of any matter like illegal drugs, explosives, poisons etc.

 

What does Forensic Scientists and Forensic Chemist do ?

Forensic Scientists examine and analyze evidence or matter obtain from crime scenes. Forensic chemists conduct analysis of matter forensic chemistry. While other forensic scientists do other analysis like fingerprinting, handwriting analysis, DNA, trace evidence examination, fire and explosives examinations, forensic toxicology, digital evidence and many other analysis.  After doing all analysis they develop objective findings that can assist in the investigation and prosecution of person who has done crime or release the innocent person.
