Why Biological evidence in forensic chemistry are very important?

The study of evidence in court matters using forensic chemistry involves the application of chemical and biological principles. The forensic chemistry focus on the samples such as blood, saliva, semen, and DNA, which are play vital role in identification of suspects and link them to a crime scene. It is impossible to eliminate the importance of biological analysis in forensic chemistry because it is essential in solving of many criminal cases.


Suspect identification:

Biological evidence found  from the scene of the crime give information to  identify suspects. DNA, which is specific to each person and is found in biological evidence that enables forensic experts to differentiate betwean DNA samples found from a crime scene with a suspect’s DNA profile.

Build a connection between suspect and crime scence:

The relation between crime scenes and criminal suspects might be developed  using biological evidence found at the scene of the crime. For instance, the prosecution’s case can become more stronger  if the DNA of a suspect is found on a murderer weapon.


Establishing the time of death:

Biological evidence provide important information such as the about the deaths,time. This information quite helpful  for locating suspects and actual person which perform of the incident.


Patterns of blood spatter, can be utilised by forensic scientists to extract information which tells the reason of death in a homicide case.


It is quite difficult to negate the importance of biological analysis in forensic chemistry. It is essential to

  • founding suspects.
  • Bridging them to crime scenes.
  • checking out how and when people die.
  • and identification of drugs and toxic materials in a person’s system.
