No Current, No Problem: Wireless Electric Field Steers Immune Cells but Stuns Cancer Cells
Chinese Academy of Sciences
Scientists have long known that electric fields can guide cell movement by a process called electrotaxis. However, most studies rely on electrodes that touch the cell medium, creating currents that complicate the biochemistry. Now, researchers designed a wireless platform that delivers a unidirectional electric field (Wi-uEF) without measurable current. Using this system, they discovered that human neutrophils consistently migrate toward the negative side (cathode), while breast cancer cells los
