Single Microtubule Orientation on Patterned Non-fouling Surfaces

Controlled Microtubules Transport on Patterned Non-fouling Surfaces

Described is a lithographic technique used to realize high resolution tracks of the motor protein kinesin inside flow cells. The process consists of patterns of plasma polymerized PEG-like non-fouling coating on a fouling glass substrate. When in contact with a coated surface, proteins adhere exclusively to the fouling areas, thus forming kinesin tracks suited for microtubule guidance. Parallel...

Orientation and confinement of cells on chemically patterned polystyrene surfaces.

UV/ozone oxidation was combined with a photomasking technique to produce adjacent regions of different chemistry on polystyrene (PS) surfaces. The surface chemistry and topography were studied using AFM, XPS and contact angle measurements. The physicochemical patterns were visualised by the condensation of water vapour upon the surfaces and by the differential attachment of Chinese hamster ovar...

Fouling and Fouling Mitigation on Heat Exchanger Surfaces

Flow analysis and fouling on the patterned membrane surface

One of the key issues in membrane technology is to avoid fouling which is formed on the membrane surface. To get over this trouble, the use of a patterned surface was suggested as a way to reduce fouling. In this report, both the experimental and numerical studies were performed with a prism patterned membrane system. In our experiments, we observe the local distribution of microbials; more fou...
