Rapid and low-cost detection platform for micro- and nanoplastics

Detection and characterization of microplastics and nanoplastics in biological samples

AI summary · Read the abstract

Researchers reviewed current methods for detecting and characterizing microplastics and nanoplastics in biological samples, finding that most techniques are optimized for environmental media like water and perform poorly in complex biological matrices, and recommending improved workflows for digestion, separation, enrichment, and analysis of particles in organisms and human tissues.

Aggregate-then-concentrate microfluidics for rapid detection of nanoplastics and submicroplastics

AI summary · Read the abstract

Scientists have developed a faster, simpler way to detect nanoplastics, tiny plastic particles so small they can pass through biological barriers in our bodies, like the gut lining or even the blood-brain barrier. By clumping these particles together first before running them through a specialized filtering chip, the new method captured over 90% of nanoplastics in test samples, including polluted seawater. This matters because better detection tools could help researchers more easily study how much of this invisible plastic pollution ends up in our environment and, potentially, in us.

Analysis of Microplastics in Biological Samples: Development and Application of Measurement Techniques

This study tested Laser Direct Infrared (LDIR) imaging as a method to detect microplastics in human blood and urine, finding it works for blood after alkaline processing but not reliably for urine. Developing validated biomonitoring techniques is essential for accurately measuring how much plastic people carry in their bodies and tracking health risks over time.

Characterization of microfluidic trap and mixer module for rapid fluorescent tagging of microplastics

AI summary · Read the abstract

Researchers developed a microfluidic lab-on-a-chip device that can simultaneously trap and fluorescently label different types of microplastics within 15 minutes, using much smaller sample volumes than conventional methods. This tool could improve the speed and efficiency of microplastic detection and monitoring in water samples.
