Abstract: Devices for detecting microorganism strains or target cellular analytes are provided. The device includes a filter holder, the filter holder comprising a tip portion; a nonwoven article disposed on the tip portion of the filter holder; and an adaptor attacked to the filter holder, the adaptor defining an aperture. Methods of detecting microorganisms and/or cellular analytes in a fluid sample using the devices are also provided. The method includes obtaining the device; placing a lumened or cannulated device in fluid communication with the device; and passing a fluid sample suspected of containing at least one microorganism strain or target cellular analyte from the lumened or cannulated device through the device and contacting the nonwoven article. The method further includes contacting the nonwoven article with at least one detection reagent and detecting the presence of the at least one microorganism strain or target cellular analyte concentrated by the nonwoven article. Kits and systems including the devices are also provided.

Abstract: An electrical property sensor is presented that includes a printed circuit board with a first face separated from a second face by a thickness, the first face having a length and a width. The sensor also includes an aperture extending from a first face of the printed circuit board to a second face of the printed circuit board. The aperture includes a receiving electrode and a transmitting electrode. When a fluid flows through the aperture and a voltage is provided at the transmitting electrode, a cunent flow is measured at the receiving electrode.

Abstract: Sensored mixer, comprising a mixing device for mixing two or more components to produce a mixed liquid at a mixer output, and a property sensor for determining a property of a liquid, the property sensor comprising a) a channel comprising a sensing zone through which the liquid flows; b) two electrodes for generating an electric field of one or more sensing frequencies in the sensing zone; c) a data storage device comprising a pre-stored set of calibration data representing calibration impedance responses measured previously at the one or more sensing frequencies and at different property values of the property of an identical liquid; and d) a device to repeatedly i) generate between the electrodes an electric field of in the sensing zone; ii) sense between the electrodes, a response impedance; iii) derive from the response impedance a property value of the property of the liquid, using the pre-stored set of calibration data representing calibration impedance responses, wherein the property sensor is in fluid communication with the mixer output such that the mixed liquid can flow from the mixer output through the sensing zone. A method for sensing a property of the liquid and a data set of calibration data representing calibration impedance responses usable with the sensor and the method are also disclosed.
