Surface patterning: more than just scratching the surface.
The ability to pattern surfaces with monolayers and multilayers is a central focus of numerous chemical studies because of the implications in fields ranging from sensor design to microelectronics. Goals vary from patterning single molecules at the sub-nanometer scale to forming vast assemblies over macroscopic areas. Moreover, this chemistry can range from simple homogeneous systems to mixed m...
متن کاملControlling cell shape on hydrogels using lift-off patterning
Polyacrylamide gels functionalized with extracellular matrix proteins are commonly used as cell culture platforms to evaluate the combined effects of extracellular matrix composition, cell geometry and substrate rigidity on cell physiology. For this purpose, protein transfer onto the surface of polyacrylamide hydrogels must result in geometrically well-resolved micropatterns with homogeneous pr...

متن کاملA combined-nanoimprint-and-photolithography patterning technique
We propose a new lithography technique that combines the advantages of nanoimprint lithography (NIL) and photolithography. In this combined-nanoimprint-and-photolithography (CNP) technique, we introduce a hybrid maskmold made from UV transparent material and with a light-blocking metal layer placed on top of the mold protrusions. We demonstrate that the CNP method using such a hybrid mold can a...
متن کاملDeformable Surface Matching for Statistical Shape Analysis
We propose a deformable surface model for matching anatomically homologous points for a specific region of interest (ROI), based on both surrounding intensity structures and shape characteristics. The initial estimate of the deformable mesh for the individual ROI was derived by transforming the template mesh to the individual image space using nonlinear warping. For the deformable surface model...
