An apparatus for optically-verified de novo DNA synthesis includes a microfluidic system that has channels leading in and out of a synthesis chamber having a functionalized region on a floor thereof on which a single-strand of DNA to which a nucleotide is to be attached can be fixed. The chamber is in optical communication with both an illumination system, which excites an electron in a fluorophore that is attached to the DNA strand, a detection system, which detects a signature photon emitted as the excited electron decays into its ground state. |
