Dynamic droplet behavior for analyte localization on phase change liquid infused surfaces

Researchers developed surfaces that can switch between slippery and sticky states using temperature-controlled phase-change oils, allowing evaporating droplets to concentrate their contents — including microplastics — into a tiny, easily analyzed spot. When tested on real microplastics from bottled drinking water, the technology successfully localized particles for detection, offering a practical new method for detecting trace levels of microplastics in water without complex laboratory equipment.
