METHOD FOR FORMING MOLECULAR SEQUENCES ON SURFACES

摘要

A method for forming molecular sequences (10) includes derivatizing an unconfined substrate (12) surface with at least one linker (14) containing a protected reactive group (PL). The substrate (12) is contacted with a solution (16) containing a photogenerated reagent precursor (18) and a buffer and/or a neutralizer (20). A photo generated reagent (22) is generated in at least a portion of the solution (16). The photogenerated reagent (22) is configured to initiate the formation of at least one active region on the substrate (12) surface. A monomer (24) is coupled to the active region.
