| abstract |
Methods for fabricating chemical arrays, such as biopolymer arrays. The method may include depositing drops which contain probes or probe precursors from positions spaced from the surface onto the feature locations, so that each of the probes or probe precursors binds to the different feature locations. This is repeated as needed at the same feature locations so as to form the array. Drop spacing may be controlled based on deposited drop splat dimensions. Apparatus, computer program products, and arrays are also provided. |
