A self-assembled molecular film of a water-soluble cobalt tetrasulfophthalocyanine was deposited on a gold substrate premodified with poly(diallyldimethylammonium chloride). The process of layer-by-layer assembly on the gold substrate was characterized using UV-Vis, Raman spectroscopy, ellipsometry, contact angle measurements, atomic force

The directional cell migration plays a crucial role in a variety of physiological and pathological processes. It can be controlled by the gradient cues immobilized on the substrate. The poly(sodium 4-styrenesulfonate) (PSS)/poly(diallyldimethylammonium) chloride (PDADMAC) multilayers were post-treated in a gradient
