  • Patent number: 10975407
    Abstract: A composition for use in extending a molecular chain includes a carrier group and a payload group. The carrier group comprising a signaling group and a blocking group. A first bond bonds the payload group to the carrier group and a second bond bonds the signaling group to the blocking group. The first and second bonds are selectively cleavable such that the first bond is cleavable without cleaving the second bond. The payload group is to be attached to the molecular chain, while the blocking group is to block further attachments to the molecular chain once the payload group has been attached. The signaling group comprises a photon emitter that emits a signature photon in response to interrogation by an interrogatory photon. The carrier group transitions from a loaded state to an empty state upon cleavage of the first covalent bond.

  • Publication number: 20190354871
    Abstract: A parallelized chain-synthesizing technique includes capillary tubes, where each tube provides multiple locations or addresses where a specific arbitrary sequence for polymeric chains can be synthesized. An optical addressing system selectively delivers light to the locations to mediate or control reactions in the tubes.
