  • Patent number: 11946872
    Abstract: A system for monitoring an analyte concentration in liquid is provided. The system includes a coupon comprising an absorbent body with a window through the absorbent body wherein the liquid is maintained in said window by capillary action and surface tension. A reactant is in the absorbent body wherein the reactant is capable of diffusing into the window to react with an analyte in the liquid, or the reactant is able to react with the analyte within the coupon itself, with color-indicating by-products of the reaction diffusing into the window, wherein the analyte is present in an analyte concentration, to form a reactant with a color wherein the color has an intensity which correlates to the analyte concentration. A light source is provided which is capable of passing light into the window wherein the light is attenuated by the color proportional to the analyte concentration to form attenuated light. A detector is provided which is capable measuring an intensity of the attenuated light.

  • Patent number: 11221473
    Abstract: Devices and methods for super-resolution optical microscopy are described. Devices include an optical multiplexer to develop an excitation/illumination optical beam that includes alternating pulses of different profiles. Devices also include a signal processing unit to process a sample response to excitation/illumination beam and to subtract the neighboring pulses of the different profiles from one another on a pulse-to-pulse basis. Devices can be incorporated in existing confocal microscopy designs. As the subtraction effectively reduces the volume of the response signal, the spatial resolution of the systems can be markedly improved as compared to previously known optical microscopy approaches.
