Particles are everywhere—from the air we breathe to the water we drink and the medicines we take. And when it comes to characterizing particles, size really does matter. The most biologically and environmentally relevant particles are often the hardest to analyze—because they’re too small, too fluorescent, or too complex for traditional techniques.
In this webinar, Dr. Mustafa Kansiz (PSC) and Professor Andrew Ault (University of Michigan) will show how optical photothermal infrared spectroscopy (O-PTIR)—with simultaneous Raman and co-located fluorescence—uniquely enables routine, label-free, high-resolution vibrational spectroscopy of submicron and even sub-500 nm particles.
✅ In Part 1, Dr. Kansiz will give a broader overview of how O-PTIR redefines what’s possible in particulates analysis, from subvisible particles in biopharma to microplastics in water, food, and air.
✅ In Part 2, Prof. Ault will present recently published research showing how O-PTIR + Raman can characterize individual bioaerosol particles as small as 180 nm—overcoming the diffraction limit of IR and avoiding fluorescence interference in Raman.
