B2.4 - Nanoelectromechanical System Fourier Transform Infrared Spectroscopy (NEMS-FTIR) for Nanoplastic and Polymer Degradation Analysis

Year: 2025

Type: conference-paper

Abstract: We introduce a novel application of photothermal infrared spectroscopy based on nanoelectromechanical systems (NEMS), integrated with a commercially available FTIR spectrometer (NEMS-FTIR).We successfully detected 1 ng of polystyrene (PS) and 1 ng of polypropylene (PP) nanoplastic particles with diameters of 100 nm and 54 nm, respectively.As a case study, we detected small amounts of degradation products originating from plastic tubing.The technique enabled high-resolution spectral identification of samples from microliter to nanoliter volumes on NEMS chips.
