A better Evaluate A number of the Essential Elements of Forensic Science

The subject find more info of numerous hit Television set reveals like "Criminal Minds," "Law & Order" as well as "CSI," forensic science easily catches the attention of many people because of its various interesting facets and procedures. Likewise, it plays a highly critical role in society, especially when it comes to unsolved and mysterious cases. Let's take a better look at its definition as well as other interesting things about it.

Definition

According to the dictionary, forensic science deals with the process of recognizing, identifying, individualizing and interpreting physical evidence. After that, the crucial factors of medicine and science will be used to process such evidence for the purposes of civil law and felony administration. It makes use of various scientific disciplines including physics, chemistry and biology. Add to that, it also considers other important fields such as psychology, geology as well as computer science. Every crime scene is searched for impressions, traces of tissues and chemicals. Other vital elements to consider are substances and objects left at the scene of the crime.

Examining Biological Traces

Biological traces play a very huge role in this vital field of science. Suspects, surviving victims and the deceased person are searched for all-important traces, which can actually help in the successful solving of crimes. These traces include semen, hair and blood, which can be helpful in extracting DNA, which will be used for comparative analysis. DNA is highly significant in solving mysterious cases because it can really help identify people, even those whose state are beyond recognition. Hair, nails and skin are excellent sources of DNA. Likewise, chewing gums, cigarette butts and bloodstains are amongst the most sought after biological traces.

Examining Chemical Traces

Quantitative and qualitative analyses are performed on chemicals to help solve crimes. Soil samples, fibers and gunshot residues can help a lot in forensics. In addition, forensic scientists can also analyze fire debris, paints and drugs. To help solve fire-related crimes and incidents, it is good to have a look at different kinds of elements such as gasoline and kerosene.

Analyzing Physical Evidence

In addition to chemical traces and biological traces, it is more critical to examine all the available physical evidence. Handprints, footprints and fingerprints belong to this category. Moreover, tool marks, cut marks and tire marks can also be very helpful in forensics.

Additional Information and Other Vital Details

When analyzing biological samples, the critical method is polymerase chain reaction. After that, the results will undergo gel electrophoresis. Other valuable methods in forensics include liquid chromatography, gas chromatography and solid-phase micro-extraction. Forensics has various subdivisions such as digital forensics, criminalistics and computational forensics. Other notable fields include forensic DNA analysis, forensic archaeology and forensic anthropology.
