We combined biochemical and topographical patterning to achieve motor-driven microtubule gliding on top of microfabricated pillar arrays with limited and controllable surface interactions of gliding microtubules. Kinesins immobilized on pillar heads pushed microtubules from the top of one micropillar to the next bridging up to 20 mum deep gaps filled with(More)
We present herein an innovative technique for decorating soft polymer surfaces with metallic nanostructures fabricated by diblock copolymer micelle nanolithography. Thus far, such nanolithography has been limited to plasma-resistant inorganic substrates such as glass. Our new development is based on the transfer of nanopatterns from glass to soft(More)
A microtransfer technique for micropattern fabrication using a dithiol macromolecular linker is suggested by transferring a conventionally photolithography-prepared gold microarray on a hard inorganic substrate to a polymeric substrate. The linker was synthesized by end-capping a poly(ethylene glycol) (PEG) chain by the thiol groups. The efficiency of this(More)
Mechanical stress is a decisive factor for the differentiation, proliferation, and general behavior of cells. However, the specific signaling of mechanotransduction is not fully understood. One basic problem is the clear distinction between the different extracellular matrix (ECM) constituents that participate in cellular adhesion and their corresponding(More)
