Images of tip. (A) Ceramic tips with cross sectional diameters of 50, 83, 109, and 132 microns, all of which have been successfully used to fabricate microarrays. (B) Stainless-steel slotted tips and ceramic tips before (left) and after (right) printing ∼100,000 microarray elements. The stainless-steel tips are considerably deformed, but the ceramic tips are intact.
