    Abstract: A scanning micro-fluid device for an exchange of species with a surface and with an intermediate immersion liquid is disclosed. The device comprises a first and a second micro-channel comprising a fluid. The first micro-channel comprises a first aperture and the second micro-channel comprises a second aperture. They have a distance to each other in an apex area in proximity of the surface of a substrate. The surface, the apex area is immersed with the intermediate immersion liquid. The device also comprises a first electrode reaching into the fluid on the first micro-channel and a second electrode reaching into the fluid on the second micro-channel, and an apex electrode. Different voltage levels are applicable to the first, the second and the apex electrode such that species are interacting at surface of the substrate.

    Abstract: A system having an electronic device. The electronic device has an array of chemically sensitive sensors. The sensors detect volatile organic compounds and have field effect transistors. The transistors have non-oxidized, functionalized silicon nanowires. The nanowires have surface Si atoms. The device has a plurality of functional groups that form a direct Si—C bond with the silicon nanowires, wherein Si is a surface Si atom and C is a carbon atom of the functional group. The functional groups are selected from the group consisting of: alkyl, cycloalkyl, alkenyl, alkynyl, aryl, heterocyclyl, heteroaryl, alkylaryl, alkylalkenyl, alkylalkynyl, alkylcycloalkyl, alkylheterocyclyl and alkylheteroaryl groups, and derivatives thereof, wherein said functional groups are other than methyl and 1-butyl. The plurality of functional groups are attached to 50-100% of the surface Si atoms.
