Fig. 3From: Express photolithographic DNA microarray synthesis with optimized chemistry and high-efficiency photolabile groupsScan image details of microarrays synthesized using four different activators. Only the use of DCI activator resulted in microarrays with highly homogenous features. The small features are 14 × 14 µm and the large rectangles are made up of an array of 5 × 5 of the smaller featuresBack to article page
