(a) Bright field microscopy images of the transferred hydrogel spots each containing one single B16F1 cell on the acceptor slide. Scale bar is 50 µm. (b) Distribution of the actual cell positions on the acceptor with average values as coordinate origin. At at 39 µm focus depth the standard deviation of cells amounts to 12.4 µm. (c) The histogram displays the frequencies in percent of the radial deviations from the origin with the given value in µm on the abscissa.
