Forensic technology has come a long way in recent years. Here’s a look at some of the most popular tools and techniques that forensic scientists use today.

What is forensic science?
Forensic science is the application of science to criminal and civil laws, mainly—on the criminal side—during criminal investigation, as governed by the legal standards of admissible evidence and criminal procedure.
What are the different types of technology used in forensic science?
There are many different types of technology used in forensic science, from simple tools like magnifying glasses and fingerprint powder, to complex instruments like DNA sequencers and electron microscopes. Here is a brief overview of some of the most common types of technology used in forensic science:
-Magnifying glasses and microscopes are used to examine small objects or details that are not visible to the naked eye.
-Fingerprint powder is used todust for fingerprints that might be invisible because of their location or because they are smudged.
-DNA sequencers are used to sequence DNA samples, which can be useful for identifying individuals or for determining the cause of death in cases where the body is too decomposed for traditional autopsy methods to be effective.
-Electron microscopes are used to examine small objects at a very high magnification, which can be helpful for examining things like hair or fibers.
What is forensic DNA analysis?
Forensic DNA analysis is the use of scientific techniques to identify an individual from a sample of their DNA. This type of analysis can be used to solve crimes, find missing persons, and exclude individuals from suspicion in criminal investigations.
Forensic DNA analysts use a variety of technologies to examine DNA samples, including:
-Polymerase chain reaction (PCR): This amplification technique is used to make many copies of a specific region of DNA so that it can be analyzed more easily. PCR is often used to amplify small or degraded samples of DNA.
-DNA sequencing: This technology is used to determine the order of the building blocks (nucleotides) that make up a section of DNA. DNA sequencing can be used to identify an individual’s unique genetic code.
-Capillary electrophoresis: This separation technique is used to resolve different types of nucleic acids (DNA or RNA) based on their size and charge. Capillary electrophoresis is often used in conjunction with PCR and DNA sequencing to analyze forensic samples.
What is forensic toxicology?
Forensic toxicology is the study of the effects of drugs and chemicals on living organisms. It can be used to determine how a person died, to identify a perpetrator, or to absolve someone who has been wrongly accused. Forensic toxicologists use a variety of techniques, including chromatography, spectroscopy, and mass spectrometry, to analyze samples.
What is forensic entomology?
Forensic entomology is the application and study of insects in criminal investigations. It can be divided into three main subfields: medicolegal, stored-product, and urban. Forensic entomologists often work closely with police detectives and crime scene investigators to help solve crimes.
Forensic entomologists may be called upon to determine the time of death of a victim, as well as the possible cause of death. They may also be asked to help identify the body of a victim or to determine whether a wound was inflicted before or after death. In some cases, forensic entomologists may be able to provide information about the location where a crime took place.
Forensic entomologists use a variety of different technologies in their work, including microscopes, computers, and DNA analysis.
What is forensic anthropology?
Forensic anthropology is the application of the science of anthropology to the legal process. The term “forensic” comes from the Latin word forensis, meaning “of or before the forum.” In modern usage, it is generally defined as “the application of scientific knowledge to public or legal issues.”
Anthropology is the study of humans, past and present. Biological anthropology encompasses the study of human evolution and human adaptability, including skeletal analysis and identification. Forensic anthropologists apply this knowledge to identify human remains in cases where positive identification is difficult or impossible through standard means, such as dental records or fingerprints. They may also be called upon to provide testimony in court regarding their findings.
In addition to skeletal analysis, forensic anthropologists may use a variety of other techniques to aid in identifying unknown individuals, such as:
What is forensic archaeology?
Forensic archaeology is the application of archaeological methods and scientific principles to the investigation of crime. It is a sub-field of archaeology and forensic science, and incorporates elements from other disciplines such as anthropology, forensics, psychology, and criminology.
Forensic archaeologists use a variety of techniques to recover, document, and analyze evidence from crime scenes. These methods include excavation, mapping, 3D scanning and imaging, and the use of specialized tools and equipment. They also use their skills to interpret the evidence they find in order to reconstruct events and provide investigators with information that can lead to the identification of suspects or victims.
What is forensic accounting?
Forensic accounting is the use of accounting principles and practices to investigate and resolve financial disputes. Forensic accountants are often employed by law firms, government agencies, and accounting firms. They may also be self-employed.
What is forensic psychology?
Forensic psychology is the application of psychological principles and methods to the legal system. It is a relatively new field that has grown in response to an increased awareness of the impact of psychological factors on criminal and civil proceedings. Forensic psychologists work in a variety of settings, including private practice, government agencies, and court systems.
Most forensic psychologists work with either the defense or the prosecution in criminal cases. They may be asked to assess a defendant’s mental state at the time of the crime, to determine whether he or she is competent to stand trial, or to provide guidance on sentencing. In civil cases, forensic psychologists may be asked to provide expert testimony on issues such as custody disputes or workplace discrimination.
Forensic psychologists use a variety of assessment tools, including interviews, psychological testing, and observational techniques. They also use their knowledge of human behavior to interpret evidence and make predictions about future behavior.
What is forensic criminology?
Forensic criminology is the scientific study of crime and criminals. It is a branch of criminology that uses technology to investigate and solve crimes. Forensic criminologists use a variety of techniques and tools to collect and analyze evidence. They may use DNA analysis, fingerprinting, ballistics, and other methods to identify suspects and solve crimes.
