Abstract
Methods of producing substrates having selected active chemical regions by employing elements of the substrates in assisting the localization of active chemical groups in desired regions of the substrate. The methods may include optical, chemical and/or mechanical processes for the deposition, removal, activation and/or deactivation of chemical groups in selected regions of the substrate to provide selective active regions of the substrate.
