  • Patent number: 11874247
    Abstract: Provided herein is a biosensor for detecting a target analyte in a sample comprising a first and second photoelectrode each comprising conductive substrate and photoactive material, a first and second capture probe functionalized on the first and second photoelectrode, respectively, and optionally one or more reporter moieties comprising a detectable label, wherein the first and second capture probe each, independently, provides a distance between the detectable label and the photoactive material in the presence of the target analyte, wherein intensity of detection signal dictated by the distance is generated from the first and second photoelectrode by transfer of electrons between the detectable label and the photoactive material, wherein a higher, or higher increase than in absence of sample, in the intensity of the detection signal from the first as compared to the second photoelectrode in the presence of the sample, is indicative of the presence of the target analyte.

  • Patent number: 11815783
    Abstract: A difference frequency generation optical transmitter and sum frequency generation optical receiver operating in the mid-infrared wavelength range for use in free space optical satellite communications are described. By using mid-infrared light, the transmitter/receiver can mitigate atmospheric scintillation, scattering, and other non-ideal optical effects in the communication channel. This is achieved through the use of nonlinear optical crystals designed for difference frequency generation in the case of the transmitter and sum frequency generation for the receiver. High-speed modulated communication signals can thus be frequency converted to the mid-infrared wavelength range by a relatively low cost, compact and high-power optical communication system.
