The Herbert W. Hoover Foundation supported Dr. Chelsea Rochman and her team in developing SLoPP and SLoPP-E, open-access Raman spectral libraries designed to make microplastics identification more accessible, reliable, and consistent. Published in Analytical Chemistry, the work created reference spectra for both pristine and environmentally weathered plastics, helping researchers more accurately identify the plastics they encounter in real-world samples. These pioneering libraries went on to help form part of the foundation for OpenSpecy, an open-source platform that is advancing and standardizing the way researchers analyze microplastics using spectroscopy. The project demonstrates how an early investment in foundational scientific tools can continue to ripple forward as those tools are incorporated into new technologies used by the broader research community.
