Abstract: A sample holder includes a slide, containing a depression in a surface of the slide. A cover slip is fixed to the slide over the depression so as to define a sample chamber, while leaving a loading area of the depression uncovered, so that a liquid sample deposited in the loading area is drawn into the sample chamber by capillary action.

Abstract: Devices and methods for capture of target particles in a flow. There is a plurality of flow rate-reducing structures in a flow chamber, each structure including a trapping surface shaped to reduce flow rate in a vicinity of the trapping surface. Reduced flow rate in the vicinity of the trapping surface is non-zero and has a magnitude lower than that of flow rate in other regions of the flow chamber. The reduced flow rate is sufficiently low for an attraction force acting on the target particles to overcome drag force on the target particles, to promote capture of particles in the vicinity of the trapping surface. The device may exhibit different sorting zones for capturing particles that experience different amounts and/or types of attraction force. The device may enable sorting of cells according to their level of display of specific protein surface markers.

Abstract: A particulate matter detection system has a particulate matter detection sensor, a current detection part and a control circuit part. The particulate matter detection sensor has an accumulation part, a pair of electrodes and a heater part. The control circuit part performs switching of a detection mode and a burning mode. When the burning mode being switched to the detection mode, the control circuit part supplies a lower voltage between the pair of electrodes, which is lower than an usual voltage used in the detection mode, and detects a current detected by the current detection part as the offset value ΔI. In the detection mode, the control circuit part subtracts the offset value ΔI from the detected current value to correct the detected current value.
