Abstract
Techniques for monitoring a target analyte in a sample using a polymer capable of binding to the target analyte are disclosed. A microdevice useful for the disclosed techniques includes a semi-permeable membrane structure, a substrate, a first and second microchambers formed between the membrane structure and the substrate. The first microchamber can be adapted to receive a solution including the polymer, and the second microchamber can be adapted to receive a reference solution. Environmental target analyte can permeate the semi-permeable membrane structure and enters the first microchamber and the second microchamber. Based on the difference in a property associated with the polymer solution that is responsive to the target analyte-polymer binding, and the corresponding property associated with reference solution, the presence and/or concentration of the target analyte can be determined.
