The modification of the liquid / liquid interface with 'track-etched' polye
ster membranes is reported: electrification of the modified interface gener
ates a nanoscale array. The uniformity of the membrane pens means the array
dimensions are well-defined. Results are presented for voltammetric ion tr
ansfer using membranes with pore radii of 100 and 15 nm. (C) 1999 Elsevier
