  • Composite material for the detection of chemical species
    Patent number: 11193915
    Abstract: A composite material for sensing a chemical species in a medium is provided. The composite material includes a polymer having a glass transition temperature, a porosity promoter dispersed in the polymer in an amount such that the chemical species is transportable from the medium into the composite material at a temperature below the glass transition temperature, and a chemical indicator dispersed in the composite material, the chemical indicator providing an optical response varying with a concentration of the chemical species in the composite material.
    Type: Grant
    Filed: November 28, 2016
    Date of Patent: December 7, 2021
    Assignee: INSTITUT NATIONAL D'OPTIQUE
    Inventors: Sebastien Dubus, Serge Caron, Nolwenn Le Bouch, Antoine Proulx
  • Method and system for the detection of a chemical species in solution
    Patent number: 11029293
    Abstract: Methods and systems are for determining the concentration of a chemical species in an analyte solution. At least one train of segments are injected into a microfluidic channel having a first end and a second end, each train of segments having segments of analyte solution and segments of sensing solution which are immiscible with the segments of analyte solution. The train of segments is circulated from the first end to the second end of the microfluidic channel such that a reversible chemical exchange is established between the chemical species of each segment of analyte solution and a chemical indicator of the at least one contacting segment of sensing solution. The response of the chemical indicator is measured at the second end of the microfluidic channel and the concentration of the chemical species in the analyte solution is determined based on the response.

  • Ultrasensitive detection of target using target-ready particles
    Patent number: 8765369
    Abstract: The invention relates to methods and reagents for detecting minute amounts of targets having affinity for nucleic acid. The present invention more particularly relates to target detection using aggregates of cationic polymer chains and nucleic acid capture probes linked to particles, such as controllable mobility particles.
