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 particular, the present invention provides methods and devices for generating a photogenerated reaction in solution on a substrate comprising generating a light beam using an optical device system comprising a light source and a computer-controlled spatial optical modulator comprising a digital micromirror device and using the spatial optical modulator to direct light to fluidly isolated reaction sites under conditions such that a photogenerated reaction takes place. The method and apparatus of the present invention have applications in parallel synthesis of molecular sequence arrays on solid surfaces.
