Synthesis of near-infrared-fluorophore-loaded microplastics with different compositions for in vivo tracking
Summary
Researchers synthesised fluorescent microplastic particles of different polymer types that can be tracked inside living animals using near-infrared imaging, creating a tool for studying how microplastics move through and accumulate within biological tissues. These model particles help researchers understand real-world microplastic behaviour inside organisms, which is critical for assessing health risks.
NIR-II fluorescent microplastic model particles possessing irregular shapes allow tracking their in vivo behaviors.

Near-infrared (NIR-II) fluorescent poly(ethylene terephthalate) nano-microplastics for in vivo tracking
Researchers developed a new method to track nano-microplastics inside living animals in real time using near-infrared fluorescent imaging. By embedding a special dye into common PET plastic particles, they were able to follow the particles through mice after oral exposure, offering a promising tool for studying how plastics of different sizes behave inside the body.
Near-Infrared-II In Vivo Visualization and Quantitative Tracking of Micro/Nanoplastics in Fish
Scientists developed a new near-infrared imaging technique to track micro- and nanoplastics inside living zebrafish in real time, overcoming limitations of previous detection methods. They found that both sizes of plastic particles accumulated mainly in the gut, with microplastics concentrating more in the front sections and nanoplastics distributing more evenly. This tracking tool helps researchers better understand how plastic particles move through and accumulate in living organisms, which is essential for assessing the risks of microplastic exposure.
NIR-II Plastic Particles for Monitoring IntestinalMotility and Microplastic Deposition in Mice
Researchers developed near-infrared II (NIR-II) fluorescent plastic particles to non-invasively track microplastic movement and deposition in living mice, finding that microplastics accumulated preferentially in the intestine with slow clearance.
Label-Free Identification and Imaging of Microplastic and Nanoplastic Biouptake Using Optical Photothermal Infrared Microspectroscopy
Researchers developed a new imaging technique that can locate and identify microplastic and nanoplastic particles inside whole organisms without needing fluorescent labels. Using a method called optical photothermal infrared microscopy, they tracked polystyrene particles as small as 1 micrometer in roundworms. This tool could help scientists better understand how plastic particles are taken up by living things and where they accumulate in the body.
Challenges in assessing ecological and health risks of microplastics and nanoplastics: tracking their dynamics in living organisms
Researchers proposed a new method for tracking micro- and nanoplastics in living organisms using fluorescent monomers built directly into the plastic particles during synthesis. Current detection methods require destructive sampling and only provide static snapshots, missing the real-time movement of particles through biological systems. This fluorescent monomer approach is designed to enable continuous, stable imaging of plastic particles as they move through complex biological environments.
