Detecting, Identifying, and Analyzing Body Fluids Using Raman Spectroscopy

SupreMEtric LLC is a startup company that originated from research at the University at Albany that focuses on modernizing forensic science. The company utilizes laser spectroscopy and complex statistical modeling to create a non-invasive way to identify biological fluids at crime scenes.¹ Their primary objective is to offer law enforcement and forensic laboratories a universal, rapid tool for analyzing evidence without damaging the samples.¹ Significant financial backing for this innovation has come from the National Science Foundation and the Department of Justice, including nearly $1.3 million in recent federal grants.¹ These resources are currently being used to transition their patented technology from a laboratory setting into a commercially available product for criminal justice professionals.¹ Through these partnerships, SupreMEtric LLC’s main objective is to improve the accuracy and efficiency of forensic investigations.

Igor Lednev, a Distinguished Professor and Williams-Raycheff Endowed Professor at the University at Albany, is the Founder and CTO of SupreMEtric LLC. At Pittcon 2026, which took place in San Antonio, Texas, Lednev updated us on the latest progress made by SupreMEtric LLC in applying Raman spectroscopy for the detection, identification and analysis of all main body fluids.

At Pittcon, Lednev delivered a talk titled, “Raman Spectroscopy and Machine Learning for Forensic Purposes Biomedical Applications.” Part 1 of our interview with Lednev focused on his talk, which was part of the Pittsburgh Spectroscopy Award symposium at Pittcon honoring his receiving of the award for 2026.² We also discussed the application of advanced statistics in forensic analysis, focusing most of our conversation on the development of software for Raman spectroscopic data analysis.³

Spectroscopy will be continuing to provide coverage of the Pittcon 2026 conference on an ongoing basis as we report back from San Antonio. You can stay up to date with our coverage of the Pittcon 2026 conference here.
