Real-time tracking of microplastics in mice using second near-infrared (NIR-II) fluorescence imaging

Caption

Microplastic particles of polypropylene, polyethylene, and polystyrene were loaded with IR-1061 and orally administered to mice. NIR-II imaging under 980 nm irradiation tracked their gastrointestinal accumulation and subsequent excretion from 30 minutes up to 48 hours.
