Abstract
A surface covered with a nanopatterned, regularly spaced array of SiO2 bloc ks is obtained by coating silica with a block copolymer, selectively removi ng one polymer from the layer, depositing SiO2 in the voids, and finally de grading the second polymer. The Figure shows an AFM image of a finished sam ple. Rough surfaces of this type are very promising candidates for sensor a nd lab-on-a-chip applications.
