Precise manipulation and transportation of micro-sized droplets is a challenging task, yet crucial for biomedical and industrial applications. A research team led by a scholar from the City University of Hong Kong (CityU) has successfully developed a novel droplet manipulation method called "WRAP" which can transport droplets of different sizes and compositions by electromagnets or programmable electromagnetic fields. The research team believes that this innovative method has great potential in developing next-generation microfluidics and in the detection of respiratory droplets bearing COVID-19 and other pathogens landed on the surface.
