In addition, degradation of biological samples is another major problem in forensic science which affects the investigation process and misleads the result. Conventional methods are effective but are insufficient to estimate accurate and precise time of death or PMI. Postmortem interval (PMI) estimation is a recurring problem in the field of forensic medicine. Conclusion With the help of this review article, an attempt was made to elucidate how nanotechnologies could be crucial in addressing current forensic investigation issues such as collection and analysis of evidence from the crime scene and how these technologies may be helpful in preventive forensic and security measures. Moreover, some crucial forensic issues such as cost and time effectiveness, wide availability, accuracy, and reliability of results are major concerns in forensic investigation and security. These techniques are based on nanomaterials that are able to provide either improved performance over conventional techniques or enable to collect information from a crime scene that would not otherwise have been possible ever. These advances in forensic technologies have mainly been focused on analytical techniques. Main text In forensic science, nanotechnology majorly is applied to develop reactive (‘smart’) materials micro-chip technology nanomanipulators nanoimaging tools for visualization. In recent years, few of them have been shown interest to apply nanotechnology for forensic purposes which are related to societal or community issues. Systems and DNA databases applications of mitochondrial DNA analysis pedigree analysis Įvidence preparation and legal and ethical considerations.įor academic programs in the forensic sciences see the listing at the American Academy of Forensic Sciences web site.Abstract Background Generally, material scientist discussing new-fangled nanotechnology research and its conversation turns to the commercial aspects or potential issues around health, safety, and the environment. Haplogrouping and analysis RFLP analysis methods PCR-based typing systems automated Maintained continuous versus discrete allele systems DNA isolation methods Y-chromosome Repetitive DNA in the human genome origin of genetic polymorphisms and how they are Other elective courses to consider outside the department would be: anthropology,īiochemistry, population genetics, and evolutionary biology.įorensic molecular biology emphasizes molecular techniques such as DNA profiling and Techniques (BMS 558), Molecular Genetics (BMS 529), and Bioinformatics (BMS 593). Sciences majors should include elective laboratory courses such as: Recombinant DNA In addition to the core sequence of course work, Biomedical Forensic molecular biology:įorensic molecular biology involves the study of human and mitochondrial DNA (may Elective courses recommended for forensic pathologyĪre: BMS 307, Human Anatomy BMS 582, Histology BMS 569, Neurobiology and BMS 561, Or a large city medical examiner's office and speak with the pathologist, investigators,Īnd lab techs about their experiences. Along with these, arrange for a tour of the local, Also, take a human anatomy course providing cadaver experience (such asīMS 307, Human Anatomy), and take a physical anthropology course (such as ANT 363, Listing of forensic science links is found at the College of American Pathologists web site. Highly recommended that you read Death to Dust: What happens to dead bodies?, by Kenneth Shows or books about forensic pathology, all of which are greatly sanitized. Forensic pathology:Īs a CMB major, make sure you have not been over-enamored by the popular television It has been estimated thatĪn additional 10,000 forensic scientists would have to be hired to reduce the DNAĪnalysis time below the level of a 30-day wait. There about 10,000 forensic scientists working in 500 labs across the United States,īut the backlogs of evidence to be analyzed are massive. Recommendationsįor the forensic pathology and forensic molecular biology are outlined below. With specific elective courses in molecular biology is recommended. If your interest is in forensic molecular biology, a major in biomedical sciences With specific elective choices in human anatomy and human physiology is recommended. If your interest is in forensic pathology, a major in biomedical sciences The chemistryĭepartment provides the kind of background you need if your interest is in forensicĬhemistry. Among the most common are:įorensic chemistry, forensic pathology, and forensic molecular biology. The forensic sciences have a number of specializations.
