Forensic science leverages a broad spectrum of scientific disciplines to analyze evidence, reconstruct events, and ultimately, contribute to the administration of justice. Chemistry, in particular, forms a cornerstone of forensic investigations, providing analytical techniques and methodologies essential for identifying, characterizing, and comparing trace evidence. This article delves into the multifaceted applications of chemistry within forensic science, exploring specific techniques, their underlying principles, and real-world case applications. At its core, forensic chemistry focuses on the rigorous chemical analysis of evidence recovered from crime scenes or related to legal investigations. This analysis aims to determine the composition, structure, and properties of various materials, providing crucial insights into their origin, potential links to individuals or locations, and relevance to the case. Several types of evidence are routinely subjected to chemical analysis:

The choice of analytical technique depends on the nature of the evidence and the information sought. Latent fingerprints, invisible to the naked eye, require enhancement techniques to become visible and suitable for analysis. Chemistry provides several methods for achieving this: 20% off all Gift Cards for December! 💌 Treat yourself or a loved one this month!Ends in : : : If yes, check out Alison’s Free LMS here!

Historically, one of the earliest forensic biologists was Sir Alec Jeffreys in 1985 using DNA fingerprinting or DNA typing to individually identify humans.[1] He targeted variable number tandem repeat (VNTRs) DNA regions using restriction... Over time technology and new research methods have increased the number and type of targets to be used for identification and moved the forensic biology field into a new era with faster, more specific,... Whereas the forensic biology field started with targeting DNA regions, this field now encompasses a wide range of topics for crime investigation.

The NIJ research and development grants have expanded the areas of science every year to cover as many topics as possible for advancement in the field of forensic biology. Future research efforts will continue to push the boundaries and enhance protocols for faster, specific, sensitive measures based in scientific fact. Select a link below to see a subset of topics, targets, and technologies that have been funded for scientific research by the NIJ. Each year the NIJ receives applications from dozens of promising research projects across the nation that can advance the forensic biology field in new ways. The applications are verified for all requested information and peer-reviewed and scored by scientific experts across various fields for merit and scientific prowess prior to awarding grants for each fiscal year. Every grant that has been funded by the NIJ has a dissemination plan in place to promote the results and attract more research ideas from newer research laboratories.

Two of the main avenues for disseminating research are by publishing in journal articles or presenting at conferences or webinars. Below are statistics showing the growth in grant funding correlating with dissemination materials across various grants by fiscal year. As shown, many of our awards are presented at various events and published in many different journals. Many of the events are hosted by scientific communities, but numerous research grants have also hosted events attended by scientists across the globe. There has also been software, databases, and research data disseminated for public use via easily accessible sites (e.g., GitHub). Below are short lists of common events and journals that have been utilized across many of the funded awards for dissemination of the research endeavors to the forensic community.

Sarah Lee AI generated Llama-4-Maverick-17B-128E-Instruct-FP8 6 min read · June 10, 2025 Forensic biology is a crucial aspect of modern crime investigation, utilizing the latest scientific techniques and methodologies to analyze biological evidence and solve crimes. In this article, we will delve into the world of forensic biology, exploring the principles, techniques, and applications that make it an indispensable tool in the pursuit of justice. Forensic biology is the application of biological principles and techniques to aid in the investigation of crimes. It involves the analysis of biological evidence, such as DNA, blood, saliva, and other bodily fluids, to help identify suspects, reconstruct crime scenes, and solve crimes. The fundamental principles of forensic biology are rooted in the understanding of the unique characteristics of biological evidence and the ability to analyze and interpret this evidence using various scientific techniques.

Biological evidence can take many forms, including: Each type of biological evidence requires specialized techniques and methodologies for analysis, and the choice of technique depends on the nature of the evidence and the question being asked.
