title: The selectivity of electrosynthesised polymer membranes depends on the electrode dimensions: implications for biosensor applications.
abstract: A biosensor selectivity coefficient defined for poly(o-phenylenediamine) electrosynthesised onto Pt microdisks and cylinders was unexpectedly found to change as the scale of the electrodes decreased, mainly due to enhanced permeability of a ubiquitous interference species in biological systems, ascorbic acid.
