            Forensic science also called forensics is the application of science to criminal and civil laws. Forensic science uses highly developed technologies to discover scientific evidence in a variety of fields.

            Modern forensic science has a broad range of applications. It is used in civil cases such as forgeries, fraud or negligence. It can help law-enforcement officers to determine whether any laws or regulations have been violated in the marketing the foods and drinks, the manufacture of medicines, or the use of pesticides on crops. It can also determine whether automobile emissions are within a permissible level and whether drinking water meets legal purity requirements. However forensic science is most commonly used to investigate criminal cases involving a victim such as assault, robbery, kidnapping, rape or murder.

           Forensic scientists collect, preserve and analyse scientific evidence during course of an investigation. Forensic science uses sophisticated laboratory techniques to detect the presence of substances in the victim, in the suspected criminal or at the crime scene. Forensic examination of substance found at a crime scene often establish the presence of the suspect at the scene.

              One of the oldest techniques of forensic science is dusting the scene of a crime for finger prints, impressions of the fingertips left on surfaces touched bare-handed because no two fingure prints are the same, finger printing provides a positive means of identification. Computer technology now allows law-enforcement officers to record fingerprints digitally and transmit and receive fingerprint information electronically for repaid identification.

          Forensic science as practiced today is a highly developed field using electron microscopes, lasers, ultraviolet and infrared light, advanced analytical chemical techniques, and computerized data banks to analyze and research evidence.
