Forensic biology is the application of biological principles and techniques in the investigation of criminal and civil cases. [1] [2]Forensic biology is primarily concerned with analyzing biological and serological evidence in order to obtain a DNA profile, which aids law enforcement in the identification of potential suspects or unidentified remains.
Forensic palynology is an evolving forensic science application. And is mostly utilized in countries such as New Zealand, Australia, and the United Kingdom. [1] It is relatively "small, disparate, and fragmented" compared to the other approaches, thus, there is no thorough guide to achieve the best practice in forensic palynology. [10]
Forensic limnology – analysis of evidence collected from crime scenes in or around fresh water sources. Examination of biological organisms, in particular, diatoms, can be useful in connecting suspects with victims. Forensic linguistics – deals with issues in the legal system that requires linguistic expertise.
Biological homochirality. What is the origin of homochirality in living organisms? In biological organisms, amino acids appear almost exclusively in the left-handed form and sugars in the right-handed form. Homochirality is an obvious characteristic of life on Earth, yet extraterrestrial samples contain largely racemic compounds. [7]

Entomological evidence collection is the process of collecting evidence based on insect clues used in criminal investigations.If evidence is not carefully preserved at a crime scene after a death, it may be difficult or impossible for an entomologist to make an accurate identification of specimens, if for example, all morphological characteristics are not preserved.
DNA profiling (also called DNA fingerprinting and genetic fingerprinting) is the process of determining an individual's deoxyribonucleic acid characteristics.DNA analysis intended to identify a species, rather than an individual, is called DNA barcoding.
The collection method used is entirely based on what the evidence type is and the surface it is on. It is also important to note that great care must be taken to prevent contamination of the evidence with other substances (such as natural oil and sweat on the hand of the collector).
