This paper demonstrates the use of optical photothermal infrared (O-PTIR) spectroscopy for the detection, identification, and localization of microplastics in tissue samples.
Eoghan Dillon, originally from Dublin, Ireland, earned his BSc in physics from TU Dublin and completed his PhD in Chemistry at Rice University in 2012, focusing on CO₂ capture using functionalized nanocarbons. He has authored multiple peer-reviewed publications and presented at major U.S. conferences including ACS, MRS, and BPS. Eoghan began his career at Anasys Instruments, specializing in AFM-based techniques like nanoscale IR and thermal analysis. He is currently the worldwide manager of applications and business development at Photothermal Spectroscopy Corp, where he leads efforts in advancing O-PTIR and simultaneous Raman spectroscopy across life sciences, polymers, and contamination analysis.
