Technologies Used In Forensic Science (2023 and Earlier)
Last but not least, this is a compilation of past developments in forensics technologies that were archived from 2023 and earlier.
DNA Phenotyping
Although samples of DNA recovered from a crime scene can be compared to identify a suspect and DNA can also be used to determine a suspect's physical characteristics. Since DNA contains 23 chromosomes that code for appearance, forensic scientists can sequence a DNA sample and give investigators classify and categorize characteristics of the suspect, such as eye color, skin color, and hair color. More recent methods can anticipate age and biological background.
Biosensors for Fingerprint Analysis
Being a forensic science student, you may be aware that fingerprint of a crime scene is generally matched to a suspect by comparing them just like the DNA. Nevertheless, fingerprints can be unclear and difficult to read sometimes. Hence, forensic scientists are now using biosensors for fingerprint analysis. This technique is generally used to examine the tiny traces of bodily fluids found in fingerprints in order to recognize the suspect. Moreover, data that also can be detected include medications, age, gender, and lifestyle.
Immunochromatography
A little sample is dropped onto a prepared test strip in immunochromatography, a technique for testing for illnesses. Covid, HIV, and even pregnancy tests are among the usual tests that employ this technology, and the results are comparatively fast. Immunochromatography tests are used in forensics to identify drugs and pharmaceuticals in the body fluids of individuals.
Even without being in a lab, a smartphone-based sensor has been created to analyze a spit sample using immunochromatography.
Using Stable Water Isotopes to Geolocate a Suspect or Victim Water isotopes differ from atom to atom and can have distinct signatures. By separating the isotopes in a water sample taken from a suspect or victim, scientists may now ascertain the sample's possible origin thanks to recent advancements in forensic science.
The journey the subject walked can be replicated by the isotopes if there are many samples. The number of persons present can also be ascertained by different means of isotope detection.
Forensic Palynology
Among forensic scientists, forensic palynology is a relatively recent field. Forensics can employ paleontology, the study of pollen, spores, grains, and seeds, to pinpoint a subject's location. Little spores and pollen can land on clothing and skin almost unnoticed. These trace components may now be collected, compared, and used as evidence thanks to methods that scientists have developed.
