Abstract
This invention provides method and apparatus for performing chemical and biochemical reactions in solution using in situ generated photo-products as reagent or co-reagent. In some embodiments, the present invention provides methods and devices for generating one or more selected multimers at specific reaction sites on a substrate comprising contacting the substrate with a liquid solution comprising photo-reagent precursors, isolating the reaction sites, selectively irradiating the reaction sites with a digital micromirror device, and contacting the substrate with monomers. The method and apparatus of the present invention have applications in parallel synthesis of molecular sequence arrays on solid surfaces.
