➀ Researchers at KTH Royal Institute of Technology have developed a faster and more precise method of elasto-inertial microfluidics for separating particles in fluids, which can be used for studying microplastics in drinking water or analyzing cancer cells from blood. ➁ The improved technique offers potential uses in medical testing, environmental monitoring, and manufacturing, enabling quick sorting of cells or removal of pollutants in water. ➂ The microfluidic device features specially engineered channels that can handle large amounts of fluid quickly, making it suitable for fast and continuous separation of particles.
