1. Identify individuals:
* DNA profiling: Using DNA extracted from biological evidence (blood, saliva, hair, etc.) to identify suspects or victims, or to establish familial relationships.
* Forensic anthropology: Analyzing skeletal remains to determine age, sex, ethnicity, and cause of death.
2. Analyze evidence:
* Trace evidence analysis: Examining microscopic materials like fibers, hairs, pollen, etc., to link individuals to a crime scene.
* Drug and alcohol testing: Detecting the presence of substances in biological samples to establish impairment or intoxication.
* Forensic entomology: Studying insects found on corpses to estimate time of death.
3. Reconstruct events:
* Bloodstain pattern analysis: Interpreting blood spatter patterns to understand the sequence of events at a crime scene.
* Forensic botany: Identifying plants and their origins to link suspects to a location.
4. Establish timelines:
* DNA degradation analysis: Determining the time elapsed since a sample was deposited based on DNA degradation.
* Forensic toxicology: Examining the concentration of drugs or toxins in biological samples to determine the time of exposure or death.
5. Solve crimes:
* Cold case investigations: Using advanced techniques to re-examine old evidence and identify suspects.
* Mass disaster identification: Identifying victims in large-scale tragedies.
Overall, forensic biotechnology aims to provide scientific evidence that can help solve crimes, establish the guilt or innocence of individuals, and ensure justice is served. This field continues to evolve rapidly, with new technologies and techniques constantly emerging to address the challenges of forensic science.
