Molding of three-dimensional microstructures of gels.
This Communication describes the use of patterned elastomeric stamps to mold, release, and stack hydrogels into three-dimensional microstructures. Molding of gels against stamps derivatized by a hexa(ethylene glycol)-terminated self-assembled monolayer or by an adsorbed monolayer of bovine serum albumin allowed the application of several soft lithographic techniques (replica molding, microtransfer molding, and micromolding in capillaries) to the microfabrication of gels. We describe procedures to generate coplanar or bilayered composites of gels.
