  • Patent number: 9658206
    Abstract: A method for multiplex characterization of individual particles by their size, shape, mechanical properties (deformability), and chemical affinity to recognition agents. The analysis can be performed from concentrated solutions. The method detects transient sticking of particles in the pore and points to its location along a pore axis. If a pore is decorated with a recognition agent for an analyte present in a solution, it is possible to distinguish specific binding at the place of the recognition agent, and non-specific adsorption of the analyte. The method confirms whether any individual particle or hydrogel completely translocates the pore and allows unambiguous detection and characterization of multiple particles or hydrogels in the pore, which would previously corrupt the results, so that higher analyte concentrations can be used for faster analysis.

  • Patent number: 9599600
    Abstract: A sensor control apparatus controls a gas sensor by means of digital control and restrains a decrease in accuracy of pump current control. A gas detection system includes such a sensor control apparatus. The sensor control apparatus includes a reference voltage generation section, and can change the maximum current range of pump current Ip in the current DA conversion section. The sensor control apparatus can set the maximum current range of the pump current Ip to a proper range in accordance with the type or characteristic of a gas sensor to be controlled. Namely, in the case where a gas sensor has a small sensor maximum current, the maximum current range of the current DA conversion section is changed to a range determined in consideration of the sensor maximum current of the gas sensor, which restrains a decrease in the accuracy in controlling the pump current Ip.
