Evaluation of in vivo and ex vivo biodistribution using Cy5.5-COOH-labeled PP (Cy-PP) microplastics. (a) Fluorescence images of ICR mice with oral administration of corn oil, Cy-PP (approximately 5 µm), and Cy-PP (10–50 µm) at 0.5 and 24 h. (b) Fluorescence signals intensity of the entire body of ICR dependent on time. (c,d) Ex vivo images and fluorescence intensities for each organ of Cy-PP microplastics-administered ICR mice at 24 h. (e,f) Fluorescence images and intensity graphs of feces collected 24 h after Cy-PP administration.
