Abstract
A method of forming a permselective layer on preselected areas of a substantially planar sensing device is disclosed. The claimed method includes establishing and confining a liquid film, derived from a silane compound mixed in a suitable solvent, within a predetermined area of the sensing device. The process relates to photolithographic imaging and developing methods coupled to a film-curing step that provides a patterned permselective layer having the desired semipermeable characteristics.
