Abstract: A method for determining the concentration of an analyte within a volume located between the cornea and the iris of an eye includes determining an index of refraction of a volume disposed between a cornea and an iris of an eye, the volume including an analyte. Based upon the index of refraction of said volume, the concentration of the analyte within the volume is determined.

Abstract: Tissue substance measurement systems are arranged with highly specialized optical sources. Quantum cascade lasers are high power semiconductor lasers which are tiny in size and highly tunable with respect to wavelength. When deployed in non-invasive tissue substance measurement systems, quantum cascade lasers offer system advantages such as high accuracy, small size, convenience, efficiency, among others. These specialized semiconductors may be used with systems based upon photoacoustic principles. Systems may be formed of a plurality of quantum cascade laser in an optical source, mechanism to couple light into tissue, an acoustic detector and a signal processor. In some versions, user interfaces provide a reporting and feedback function to a user.

Abstract: A diffusion-based method for detecting activity of a biologic or chemical species is described. The method includes supplying the biologic or chemical species to a finite volume diffusion channel having a transport axis. The method further includes supplying a reactive constituent in fluid communication with the biologic or chemical species, whereby the reactive constituent is known or suspected of being reactive to the biologic or chemical species. The method further includes detecting the presence or absence of a diffusion gradient occurring between the biologic or chemical species and the reactive constituent. The presence or absence of the diffusion gradient can then be correlated to the presence or absence of activity of the biologic or chemical species.

Abstract: The present invention provides a method for detecting a molecular event, comprising (1) applying an electromagnetic test signal to a sample in which a molecular event is being detected, whereby the sample interacts with and modulates the test signal to produce a modulated test signal, and (2) detecting the modulated test signal, wherein the applying and detecting take place in a temperature-controlled environment, wherein the temperature-controlled environment comprises the sample, a radiating portion of a signal generating circuit, and a receiving portion of a signal detection circuit and wherein the applying and detecting take place in the environment at a temperature controlled to within ±0.5° C.

Abstract: A system and method for detecting a molecular event in a test sample using a resonant test structure is presented. The method includes providing a resonant test structure having a resonant response associated therewith. Next, a first resonant response of the resonant test structure is obtained when the resonant test structure is electromagnetically coupled to a reference sample, the reference sample having a known composition. A second resonant response is also obtained when the resonant test structure is electromagnetically coupled to the test sample, the test sample having an unknown composition. Subsequently, one or more first electrical parameters, such as the q-factor of the resonator, are derived from the first resonant response. One or more second electrical parameters are similarly derived from the second resonant response. The similarity or difference between the first and second electrical parameters are analyzed to determine the presence or absence of the molecular event in the test sample.

Abstract: A system and method for comparing the permittivities of test and reference samples to detect and identify molecular events is presented. A resonant detector configured to output measurement parameters when the detector is electromagnetically coupled to a supplied sample is provided. One or more permittivity coefficients is defined for the detector. A first output parameter is obtained from the detector when the detector is electromagnetically coupled to a reference sample. A second output parameter is obtained from the detector when the detector is electromagnetically coupled to the test sample. The difference between the first and second output parameters is applied to the one or more permittivity coefficients to compute the relative difference in permittivity between the test sample and reference sample.
