A 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. PDMS is integrated into the microfluidic chip as a substrate to successfully pattern and guide neurites on the PDMS surface with microgrooves.
