ClearAmphiphilic Magnetic Particles Dispersed in Water and Oil for the Removal of Hydrophilic and Hydrophobic Microplastics
Researchers developed amphiphilic magnetic particles that can disperse in both oil and water, making them effective at capturing different types of microplastics from aquatic environments.
