Warren C. W. Chan has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11802878
    Abstract: The invention describes methods and reagents useful for sequencing polypeptide molecules. The method comprises affixing a polypeptide to a substrate and contacting the polypeptide with a plurality of probes. Each probe selectively binds to an N-terminal amino acid or an N-terminal amino acid derivative. Probes bound to the polypeptide molecule are then identified before cleaving the N-terminal amino acid or N-terminal amino acid derivative of the polypeptide. Also provided are methods for the sequencing a plurality of polypeptide molecules in a sample and probes specific for N-terminal amino acids or N-terminal amino acid derivatives.

  • Patent number: 11248255
    Abstract: An automated multiplex detector system includes: (a) a nucleic acid amplification compartment for amplifying nucleic acid of one or more targets in a sample, and (b) an analysis compartment in fluid communication with the amplification compartment, the analysis compartment housing a nanoparticle-based multiplex detector capable of using the amplified nucleic acid of the amplification compartment and producing a signal that correlates with the presence of the one or more targets in the sample.

  • Publication number: 20210237085
    Abstract: Described are various embodiments of a reactive chemical exothermic heating element and system. The exothermic chemical heating element has a reactive solid holder having a channel therein with an exposed end. A reactive chemical is disposed in the channel and able to exothermically react with a suitable liquid, contained in a first vessel. On exposure to the suitable liquid, a gas is generated in the channel and a gas bubble emerges from the channel thereby limiting further suitable liquid from accessing the reactive chemical, and thus controlling the rate of the exothermic reaction and the energy released over a given time period to the suitable liquid. A second vessel may be disposed in the suitable liquid so as to heat any contents of the second vessel via a liquid bath of the second vessel.
