Microscopic image of HeLa cells on (A) non-coated and (B) 50% PPR-coated sensor surface. Holomonitor images of HeLa cells on (C) non-coated and (D) 50% PPR-coated sensor surface. For all images TE was used as the dissociation protocol. On the non-coated surface, there are no cell adhesion motifs, the cells adhere to the surface through a passive process, so the cells have a hemispherical shape.
