Externally Tunable, Low Power Electrostatic Control of Cell Adhesion with Nanometric High‐k Dielectric Films (Adv. Funct. Mater. 27/2023)

Bio-Adhesion In article number 2300732, Kripa K. Varanasi and co-workers, developed a voltage-controlled electrostatic approach for modulating the bio-adhesion of cells to surfaces. Surface zeta potential is controlled by the application of voltage across nanometric high-K dielectric film. By reducing algae cell adhesion and biofouling, the efficiency of photobioreactors for CO2 capture is enhanced. This approach can be broadly applied to cell culture, medical implants, tissue engineering and bioreactors.
