1. A device comprising:
- a. a substrate comprising a surface;
b. a non-fouling polymer layer on the surface, wherein the non-fouling polymer layer comprises a film of functionalized poly(oligo(ethylene glycol)methyl methacrylate) brush molecules, the brush molecules comprising a monomeric core group and a protein-resistant head group;
c. at least one capture region on the polymer layer, comprising at least one capture agent, wherein the at least one capture agent binds a target in a sample and the at least one capture agent remains bound to the polymer layer when exposed to the sample; and
d. at least one labile region on the polymer layer, comprising at least one detection agent and an excipient, wherein the at least one detection agent solubilizes upon contact with the sample and binds to and labels the target in the sample;
wherein the capture region and the labile region are spatially separated.
