UNF chemistry professor awarded NSF Grant to advance laser-based measurement technology

The University of North Florida has been awarded a National Science Foundation (NSF) grant to advance laser-based measurement technology in order to find more accurate and reliable chemical measurements across diverse scientific fields.

Dr. Willis Jones, assistant professor of chemistry and biochemistry, will lead the study that will pursue groundbreaking advances in laser-induced breakdown spectroscopy (LIBS), a powerful but often limited analytical technique.

LIBS uses a high-powered laser to create a small plasma that reveals the elemental compositions of solids, liquids and gases with minimal preparation. While powerful, the method is hindered by "noisy" data, poor reproducibility and sensitivity to different sample types, such as soils versus wastewater, which can distort results.

To overcome these challenges, Jones and his team of student researchers will build a custom LIBS system and pioneer new calibration strategies designed to improve trace-level analyte detection. Their work could transform not only LIBS but also other analytical technologies, offering broader applications for more accurate and reliable measurements.

Central to the project is the development of matrix-matched calibration strategies based on standard dilution analysis (SDA), an approach proven to increase accuracy and correct for matrix effects, both of which are troublesome in traditional LIBS.

This research advances scientific understanding while providing valuable training opportunities for UNF students. Undergraduate researchers will work closely with Jones on the project, gaining hands-on experience with cutting-edge technology. The LIBS technique and principles will also be incorporated into UNF's core chemistry curriculum, preparing future generations of scientists to contribute to rapidly evolving fields of study.
