  • Publication number: 20210293707
    Abstract: A well reader and actuator (100) for a well array (50) has an array of detectors, each detector for detecting a fluorescence signal from fluorophores in a respective well of the well array and an excitation subsystem for exciting the fluorophores in the wells of the well array. Embodiments of this invention can be used to carry out two important functions in a highly parallel manner: by addressing individual wells in a 32, 96, 384 etc. well array, where each well contains a potential chemical or biological reaction. The two functions are: 1) through thermal, optical or other means and combinations thereof the rate of a chemical or biological reaction is controlled or gated (e.g. colder wells inhibit a reaction, or an enzymatic reaction requires blue light to proceed); and 2) through use of fluorescent species that are sensitive to the target reaction—or reactions—an optical readout of fluorescent intensity and/or lifetime is tracked to monitor the evolution of the reaction.

  • Patent number: 11054386
    Abstract: Aspects of the invention are directed to chemical and biological molecule sensing devices, methods of fabricating the chemical sensor devices, and methods of using those devices to detect chemical and biological molecules. The chemical sensor device may comprise a chemically-sensitive vertical slit field effect transistor (VeSFET) with a chemical recognition element attached to a gate structure and/or a channel of the VeSFET. The recognition element may be capable of binding to a chemical of interest such that the binding of the chemical to the recognition element results in a modification of current flow of the VeSFET, resulting in a detectable signal. The chemical sensor device may further comprise an amplifier configured to receive the detectable signal and produce an amplified signal, and an analog-to-digital converter (ADC) configured to receive the amplified signal and to produce a digital signal that represents the amplified signal.

  • 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: 20200363398
    Abstract: A method for identifying an interaction between a pathogen and a biological agent includes providing a platform for supporting cell growth, seeding different interaction sites on the platform with different biological agents, perfusing the platform with a fluid that carries substances for promoting growth and maintenance of the cells, exposing all of the interaction sites to a solution containing viruses, and detecting evidence indicative of the interaction, the evidence comprising evidence indicative of a change in structure or composition of a medium at the interaction site. The biological agent includes cells alone or cells with another substance.
