Abstract
Ordered arrays of micrometer- and nanometer-sized wells were fabricate d by chemically etching an optical imaging fiber's distal face. Well d epth mas controlled by the etch reaction time. Well packing densities could be increased by tapering the imaging fiber's distal tip. The sma llest wells had a 50-nm depth and a 125-nm radius corresponding to a 3 x 10(-18)-L volume and a packing density of 3.6 x 10(8) wells/cm(2). Ordered nanowell arrays were used as templates to emboss polymeric fil ms with patterned nanometer-sized structures.
