| Popis: | Polyelectrolyte block copolymer micelles assembled thin film is switched in response to local photocatalytic reactions on titanium dioxide, resulting in a layer of variable height, stiffness in response to visible light irradiation. Preosteoblasts migrate toward stiffer side of the substrates. Front Cover: There are great prospects of conversion of energy of electromagnetic irradiation into pH gradients enabling also spatial regulation by localization of the irradiation spot onto a semiconductor titania surface to guide cells on a surface that promises many applications in biosciences, fundamental cell biology and microfluidics.
