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

Diffraction-limited, high-contrast photopatterning of the photoluminescence of layer-by-layer films comprising CdSe@CdS@ZnS quantum dots and polyviologen is reported. The photoluminescence of the quantum dots is initially quantitatively quenched due to ultrafast photoinduced electron transfer to polyviologen. Photopatterning is achieved by high-power
