The startup spun out of research at Princeton, where the founders drew inspiration from aquatic plants that can naturally attract microplastic. The plants have fibrous roots coated in a hydrophobic gel that pulls in pollution. "We managed to imitate the geometry and hydrophobility of the aquatic plant root," says cofounder Yidian Liu. "It has a lot of unevenness on the surface that creates little cavities for smaller pollutants to be trapped inside."
