Nanoimprinting of topographical and 3D cell culture scaffolds

The extracellular matrix exhibits several nanostructures such as fibers, filaments, nanopores and ridges that can be mimicked by topographical and 3D substrates for cell and tissue cultures for an environment closer to in vivo conditions. This review summarizes and discusses a growing number of reports employing nanoimprint lithography to obtain such scaffolds. The different nanoimprint lithography methods as well as their advantages and...
