SUNY Poly Research Associate for NanoHealth Initiatives Nicole Neu-Baker published collaborative research, "Evaluation of classification methods for identifying multiwalled carbon nanotubes collected on mixed cellulose ester filter media," with researchers from the University at Albany School of Public Health and the National Institute for Occupational Safety and Health (NIOSH).

This research is due to ongoing support from NIOSH through an Interagency Personnel Assignment awarded to Ms. Neu-Baker and is part of a long-standing collaboration between SUNY Poly and NIOSH

Abstract

"Enhanced darkfield microscopy (EDFM) and hyperspectral imaging (HSI) are being evaluated as a potential rapid screening modality to reduce the time‐to‐knowledge for direct visualisation and analysis of filter media used to sample nanoparticulate from work environments, as compared to the current analytical gold standard of transmission electron microscopy (TEM). Here, we compare accuracy, specificity, and sensitivity of several hyperspectral classification models and data preprocessing techniques to determine how to most effectively identify multiwalled carbon nanotubes (MWCNTs) in hyperspectral images."
