主权项

1. A method of fabricating a neural interface, comprising: coating a photo-curable polymer resin on a substrate,
displaying an image comprising regular pores onto the polymer resin-coated substrate using projection micro-stereolithography, thereby cross-linking the resin, and developing the imaged polymer-resin coated substrate in the presence of a first solvent system, thereby revealing an array of pores formed within a porous polymer mat, wherein the first solvent system determines a feature size of the pores, and wherein the developing step provides a reduction in the feature size of pores within the porous polymer mat, as compared to a feature size of the regular pores provided in the image.
