Abstract
A sensor may include a membrane to deflect in response to a change in surface stress, where a layer on the membrane is to couple one or more probe molecules with the membrane. The membrane may deflect when a target molecule reacts with one or more probe molecules.

11. A system, comprising:
-
a substrate; a membrane coupled with the substrate and spanning a well in the substrate; a layer on the membrane, the layer to couple one or more probe molecules with the membrane; another membrane coupled with the substrate and spanning another well in the substrate; a layer on the another membrane, the layer to couple one or more probe molecules with the membrane; a cover to enclose the well and the another well; a channel to provide fluid to the membrane; and another channel to provide fluid to the another membrane.

20. A method, comprising:
introducing fluid into a region proximate to a membrane, the fluid including one or more target molecules to be sensed, at least some of the one or more target molecules subsequently interacting with one or more probe molecules coupled with a layer on the membrane and causing a deflection of the membrane; and
measuring the deflection of the membrane.- View Dependent Claims (21, 22, 23, 24, 25, 26, 27)
