Porous multilayer-coated PDMS stamps for protein printing.
A polyelectrolyte multilayer was assembled on top of a patterned PDMS stamp employing the layer-by-layer (LbL) assembly technique. By post-treatment with a base and further cross-linking, a porous multilayer-coated PDMS composite stamp was obtained. With the pore structures acting as an ink reservoir, the multiple printing of proteins was successfully achieved without the need to re-ink the stamp.
