Skittles: A Multicolor Flow Cytometric Workflow for High-Throughput Characterization of Micro- and Nano-plastics
AI summary Read the abstract
Scientists developed a fast new lab technique called "Skittles" that can quickly detect and sort tiny plastic particles, called microplastics and nanoplastics, in water and other samples. This matters because these particles are everywhere in our environment and body, and better detection tools will help researchers figure out how much exposure we're actually getting and what health risks that poses.
Micro- and nano-plastics (MNPs), polymer particles less than 5 mm in dimension, are abundant and globally pervasive anthropogenic pollutants. However, their true abundance in natural systems remains poorly constrained by the lack of high-throughput, standardized analytical methods for their ch...

Can flow cytometry emerge as a high-throughput technique for micro- and nanoplastics analysis in complex environmental aqueous matrices?
AI summary Read the abstract
Researchers reviewed the potential of flow cytometry — a technique that rapidly analyzes individual particles — as a high-throughput tool for detecting micro- and nanoplastics in water samples, finding it excels at measuring particles smaller than 20 micrometers that other methods struggle to detect. Using fluorescent dyes to tag plastics, the approach could enable near-real-time environmental monitoring at a scale no other current technique can match.
Flow cytometry as new promising detection tool for micro and submicron plastic particles
AI summary Read the abstract
Researchers evaluated flow cytometry as a detection tool for micro- and nanoplastics, testing its ability to rapidly identify and count plastic particles in environmental and biological samples. Results demonstrated that flow cytometry offers a promising high-throughput approach for microplastic detection compared to more time-intensive conventional methods.
A novel high-throughput analytical method to quantify microplastics in water by flow cytometry
AI summary Read the abstract
Researchers developed a faster, high-throughput method using flow cytometry — a technology that rapidly counts and characterizes particles in liquid — to measure microplastics in water, achieving about 97% accuracy across multiple plastic types and sizes and offering a practical alternative to slow, labor-intensive microscopy-based counting.
An aptamer-guided flow-cytometric biosensor for simultaneous sizing and polymer identification of nanoplastics
AI summary Read the abstract
Scientists have developed a new tool that can detect tiny plastic particles, down to just 100 nanometers, far smaller than a human hair, and identify exactly what type of plastic they are, all in a single fast test. This matters because as nanoplastics show up more in our water and environment, having a reliable way to measure and classify them is a key first step toward understanding how much we're exposed to and what health risks they might pose.
