Figure 7From: Adherent cells avoid polarization gradients on periodically poled LiTaO3 ferroelectrics Summed time points of pixel analysis for spread fibroblasts between 1Â h and 18Â h of cell adhesion. The bars are the mean of four sample position. Error bars indicate the SD. The minima are clearly connected to the borders between two stripes with opposite polarization.Back to article page
