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. 1. An apparatus comprising a microfluidic system , a detection system , and an excitation system , wherein said microfluidic system includes a first manufacturing unit , wherein said first manufacturing unit includes a chamber , a first channel , a second channel , and a functionalized region , wherein said functionalized region is configured for holding a molecular chain to which a monomer is to be attached , wherein said functionalized region is disposed in said chamber , wherein said chamber is in optical communication with said detection system , wherein said chamber is in optical communication with said excitation system , wherein said first channel connects to said chamber , wherein said second channel connects to said chamber , wherein said detection system comprises a detector tuned to detect a signature photon from a fluorophore that is attached to said single strand , said single strand having been attached to said functionalized region , and wherein said excitation system comprises a light source disposed for illuminating said fluorophore , said light source being configured to stimulate a specific electronically excited state.2. The apparatus of claim 1 , wherein said microfluidic system is formed on a substrate claim 1 , said apparatus further comprising a second manufacturing unit that has the same structure as said first manufacturing unit claim 1 , wherein said second manufacturing unit is formed on said ...
