Abstract
A straightforward, inexpensive, and reliable approach to pattern electrospun nanofibers via solvent-containing agarose hydrogel stamps is reported. Complex hierarchical microstructures can be further constructed via appropriate multistep permutation of microcontact patterning and electrospinning. As a proof-of-concept application, the patterned electrospun nanofibers are employed to spatially coordinate cell orientation in microfluidic devices.

Abstract
Aligned nanofiber arrays and mats were fabricated with an electrospinning process by manipulating the electric field. The electric field was modified by insulating blocks (IBs) that were installed between the nozzle and the substrate as guiding elements to control the trajectory of the electrospinning jet flow. Simulation results showed that the electric field was deformed near the IBs, resulting in confinement of the electrospinning jet between the blocks. The balance of the electric field in the vertical direction and the repulsive force by space charges in the confined electrified jet stream was attributed to the aligned motion of the jet. Aligned arrays of 200 nm thick polyethylene oxide nanofibers were obtained, exhibiting wave-shaped and cross patterns as well as rectilinear patterns. In addition, 40 μm thick quasi-aligned carbon-nanofiber mats with anisotropic electrical property were also attained by this method.
