Feature size flexibility. A 2.25-μm resolution fluorescent micrograph of a hybridization of biotin labeled cRNAs from Bacillus subtilus and Escherichia coli to a custom DNA array. This scan was obtained using a 2.25-μm resolution arrayWoRx scanner from API. The array contains 195,000 features in 14 × 17.4 mm². From left to right, four different feature layouts were tested: 14-μm features separated by 3-μm gaps, 16-μm features in a checkerboard pattern, 16-μm features separated by 18-μm gaps, and 33-μm features separated by 18 μm.
