Characterization of Diamond Replicas Microfabricated Using Silicon Molds
Journal of Metastable and Nanocrystalline Materials, 2004Diamond replicas, concerning to the fidelity, were quantitatively evaluated in this work. We analyzed the dimensions and morphology of the silicon molds and diamond replicas by atomic force microscopy. The micrometric and nanometric characterization were performed for different substrate pretreatments.

Replica molding of picosecond laser fabricated Si microstructures
Applied Physics A, 2007This work demonstrates the fast generation and rapid replication of laser-fabricated three-dimensional conical microstructures on single-crystalline silicon. Large areas containing Si structures are fabricated by fast scanning of the focussed laser beam of a high-power, high repetition rate infrared picosecond laser system over the Si surface, in the ...

Approaching Zero: Using Fractured Crystals in Metrology for Replica Molding
Journal of the American Chemical Society, 2004This report presents a simple and convenient method to generate nanoscale fractures (cracks) in smooth, single-crystalline Si substrates. The cracks propagated as approximately straight lines along the {100} crystal planes with controllable length defined by a stabilizing backlayer.

Three dimensional metal pattern transfer for replica molded microstructures
Applied Physics Letters, 2009We report a replica molding process for simultaneously forming a three dimensional metal pattern on the surface of molded polymer microstructures. This technique uses noncovalent surface forces to guide the transfer of thin metal films from the three dimensional features of high aspect ratio poly(dimethylsiloxane) micromolds to polymeric replicates ...

Direct UV-Replica Molding of Biomimetic Hierarchical Structure for Selective Wetting
Journal of the American Chemical Society, 2008describe a one-step UV-replica molding method for fabricating a biomimetic dual-scale hierarchical structure. The use of UV-curable, acrylate-functionalized perfluoropolyethers allows for a high fidelity replication of a low-energy surface with multiscale texture, thereby directly creating a superhydrophobic surface without any complicated processing ...

Electrospun Fiber Template for Replica Molding of Microtopographical Neural Growth Guidance
Small, 2012A method for replica molding electrospun (ES) fibers on the surface of polydimethylsiloxane (PDMS) is developed for culturing and guiding of cells, instead of ES fibers. With this method, microgrooves and microstructures composed of microgrooves can be obtained.

Fabrication of NOA microfluidic devices based on sequential replica molding
Korean Journal of Chemical Engineering, 2017Polydimethylsiloxane (PDMS) microfluidic devices, though they are commonly utilized in microfluidic applications, have several limitations, such as short-term modified surface condition, swelling in the presence of organic solvents, and deformation under high pressure or when built with low aspect ratios.
