    摘要： This present invention relates generally to devices, systems, and methods for performing bioimaging at the microscopic scale and, more particularly, to devices and systems including a disposable testing device configured to perform bioimaging at the microscopic scale, and methods of performing the bioimaging using the disposable testing device. In some aspects, a testing device is provided for imaging blood cells in a blood sample. The testing device having a sample entry port for receiving the blood sample; a sample testing conduit fluidically connected to the sample entry port, the sample testing conduit including: (i) a planar member, (ii) a transparent planar member, and (iii) a plurality of spacer elements having an average spacer height and disposed between the planar member and the transparent planar member; and an imager chip forming at least a portion of the planar member.

    摘要： The present invention relates to analytical testing devices comprising a single channel with micro-environment sensors and methods for assaying coagulation in a fluid sample applied to the micro-environment sensors, and in particular, to performing coagulation assays using a single channel with micro-environment sensors in a point of care test cartridge. For example, the present invention may be directed to a sample analysis cartridge including an inlet chamber configured to receive a biological sample and a conduit fluidically connected to the inlet chamber. The conduit includes a sensor chip including a first micro-environment sensor and a second microenvironment sensor, and a fluid lock valve. The sample analysis cartridge further includes a pump configured to push the biological sample over the first micro-environment sensor and the second microenvironment sensor to the fluidic lock valve such that the biological sample is positioned over the first micro-environment sensor and the second micro-environment sensor.

    摘要： Methods and devices for determining device usability, e.g., for point of care assay devices. In one embodiment, the invention is to a method of determining device usability in a sensing device, including the steps of: providing a device comprising a first electrical pad; a second electrical pad; and a first polymer layer contacting at least a portion of the first and the second electrical pads and a second polymer layer contacting the first polymer layer and not the first and second electrical pads; applying a potential across the first and the second electrical pads; measuring an electrical property associated with the first and the second polymer layers; and determining whether the measured electrical property associated with the first and the second polymer layers has exceeded a threshold level associated with the device usability.
