    摘要: A method for detecting biomarkers with shortened test time and maximized precision. A sample from the body fluid is made to flow over a sensor surface coated with a capture antibody to allow binding of a biomarker in the sample to the capture body. An optical method detects and counts the individual binding events along the sensor surface with single molecule resolution, and difference in the binding events along the sensor surface is detected in real time and analyzed to determine the biomarker concentration.

    摘要: A method for weight and/or fitness management using a metabolic analyzer that measures metabolic data including oxygen and carbon dioxide. The metabolic analyzer includes integrated collection-detection sensors with for high efficiency and collection, high specificity and simultaneous detection of at least two metabolic signatures, including at least oxygen and carbon dioxide, in breath via a porous membrane with high density of sensing binding sites, where the porous membrane includes sensing materials such that the sensing binding sites are specific to the metabolic signatures, and change colors upon interactions with the metabolic signatures. Weight of the subject is measured using a weight measurement device and a recommendation for food intake and/or physical activity is based on at least the readings of the metabolic analyzer and weight of the subject.

    摘要: A gas-phase detection system based on detecting optochemical and optoelectrochemical signals. The sensing platform is particularly powerful for detection of nitrogen oxides at low ppbV concentrations. The optochemical analysis is based on the color development due to a chemical reaction taking place in an optimized material. The electrochemical analysis can be based on the doping level or redox potential changes of an electrochemical sensor; and optoelectrochemical detection can be based on a combination of the electrochemical and optoelectrochemical methodologies. Each independent signal can be simultaneously detected, increasing the reliability of detection.

    摘要: A rapid antibiotic susceptibility test (AST) based on the detection and quantification of the movement of single bacterial cells with a plasmonic imaging and tracking (PIT) technology. The PIT-based AST detects changes in the metabolic activity of the bacterial cells long before cell replication, and allows rapid AST for both cultivable and non-cultivable strains. PIT tracks 3D movement with sub-nanometer resolution and millisecond temporal resolution. PIT also allows simultaneous measurement of the binding kinetic constants of antibiotics and bacterial metabolic state after the introduction of antibiotics.
