A nanoporous membrane structure characterised in that it has a hexagonal array of tubes which open with pores wherein there is a substantially uniform inter-pore distance between the tubes and wherein the distance is within the range from 10-500 nm and wherein the tubes have a depth of up to 500 μm.
A method for preparing a nanoporous membrane, comprising the steps of:
- (a) preparing an aluminium film;
- (b) subjecting the aluminium film to a first anodising step;
- (c) subjecting the aluminium film to wet chemical etching;
- (d) subjecting the aluminium film to a second anodising step, wherein the conditions employed in this step are similar to or substantially the same as the conditions as used in the first anodising step.
