Charge repulsion
Web1 day ago · Because the cells naturally carry a small negative electric charge on their membrane surface, the team figured that electrostatic repulsion could be used to push them away. The idea was to create a negative charge on the vessel walls, such that the electric field forces the algae cells away from the walls.

WebIn chemistry, there are many different processes which can lead to a surface being charged, including adsorptionof ions, protonationor deprotonation, and, as discussed above, the application of an external electric field. Surface charge emits an electric field, which causes particle repulsion and attraction, affecting many colloidalproperties.
