Devices, cartridges, and sensors for analyzing a biological sample
Described herein are cartridges and devices for operating said cartridges for analyzing a biological sample, such as a blood or saliva sample. Also described herein is an impedance sensor for analyzing a biological sample. Further described herein are methods of determining a cell count or detecting an analyte in a biological sample, which can include transporting the biological sample through a sensor comprising a channel or pore; applying an electrical current or voltage to the channel or pore; detecting an impedance within the channel or pore; and determining a cell count or detecting the analyte based on the detected impedance. Also described herein is an electrowetting electrode array that is configured to transport aqueous solutions using low voltage, such as about 50 volts or less. Further described herein are methods of transporting an aqueous liquid using electrowetting electrodes. |

Microfluidic detection circuit and driving method thereof, and microfluidic apparatus
A microfluidic circuit includes a detection capacitor, having a first terminal and a second terminal that are spaced apart from one another to thereby form a space therebetween. The circuit is configured to detect a droplet present in the space by detecting a change of a capacitance value of the detection capacitor caused by a change of a dielectric constant between the first terminal and the second terminal, and to drive a formation of an electrical field formed using at least one of the first terminal and the second terminal of the detection capacitor to thereby drive the droplet to move in the electrical field. |
