Figure 3From: Adherent cells avoid polarization gradients on periodically poled LiTaO3 ferroelectrics Optical micrographs of REF52 cells on LiTaO 3 surfaces with different polarization. Cells are equally well spread on (a) positive polarization, (b) negative polarization, and (c) periodically poled stripes (40 μm period).Back to article page
