Nanoplastics (NPs) are being increasingly recognized as potential biological hazards, but their direct effects on molecular structure and cellular function remain poorly understood.

In this webinar, Assoc. Prof. Oxana Klementieva (Lund University) will present new findings based on her recent paper: Polystyrene nanoplastic exposure promotes amyloid misfolding and metabolic impairment at sublethal doses. A subcellular infrared imaging study.
This research shows how 200 nm polystyrene NPs can induce protein misfolding and impair cellular metabolism. Using submicron IR (Optical Photothermal Infrared, O-PTIR) spectroscopy, this work visualizes nanoscale biochemical changes inside cells without labels or dyes, revealing how nanoplastics act as active interfaces that alter function and protein structure, which is implicated in some neurodegenerative diseases.
Dr Mustafa Kansiz, Director of Product Management (Photothermal Spectroscopy Corp.) will provide a brief overview of submicron IR (O-PTIR) spectroscopy and application examples demonstrating how O-PTIR enables direct, label-free mapping of MPs/NPs and biomolecular changes in complex biological systems.
