A technique using digital masks without ultraviolet light to rapidly print 3-D biopolymer structures with complex microarchitectures in a microfluidic chip has been demonstrated. In this approach, a customized system is used to project light images on a photoconductive substrate in order to create localized virtual electrodes when an alternating electric field is applied across the fluidic medium...
Patterned microstructures of hydrogels have attracted significant attention due to an increasing need for developing scaffolds for tissue engineering, as carriers for drug delivery, and as extracellular matrices for biological studies. However, current tissue engineering approaches lack the flexibility required for developing complex two or three-dimensional (2D/3D) microstructures, which are used...
