The present invention overcomes a significant disadvantage of the prior art, since prior methods could not constrain {HEAD ~ the formation} or {TAIL ~ deposition} of biomolecules to a small region, due to the inability to localize the synthesis process or to restrict the migration of materials to prevent adjacent “spots” from diffusing into each other
