摘要：
The disclosed invention provides a sensing device capable of concentrating a fluid sample with respect to a target analyte and a reference analyte, and measuring the target analyte and reference analyte in the concentrated sample. The invention includes a concentrator that may include a selectively permeable membrane, or a gel having an increasing density gradient. In another embodiment, the invention includes an air or gas gap between a fluid transport channel and the concentrator. In another embodiment, the sensing device includes a driver for electronically moving a fluid sample through the channel and membrane to cause concentration. In some embodiments, the invention may also determine the change in molarity of the fluid sample with respect to the target analyte, as the sample is concentrated by the device.
