1. A device, comprising:
- (a) a substrate having a chemically selective surface;
(b) a fluidic system disposed on said substrate, said fluidic system comprising;
(i) at least one fluid path in communication with at least a discrete region of said surface, wherein said one fluid path and said discrete region together define a contained sample region on said surface, and(ii) a removable fluidic system portion;
(c) means for fastening the fluidic system to the substrate;
(d) means for engaging a first detection system, wherein the device is removably insertable into the detection system; and
wherein the first detection system comprises means for interrogating the substrate surface when the fluidic system portion is integrated with the device, and(e) means for engaging a surface-based analytical tool, wherein the surface-based analytical tool comprises means for interrogating the substrate surface as a result of removal of the fluidic system portion.

Abstract
A method and a device for detecting an analyte, including a substrate having a chemically selective surface; and a fluidic system disposed on the substrate, the manifold having at least one fluid path in communication with at least a discrete region of the surface, wherein the one fluid path and the discrete region together define a contained sample region on the surface. The fluidic system has a removable portion, wherein the removal of the removable portion of the fluidic system renders the discrete region directly interrogatable by a surface-based analytical tool.
