Estimating the term…
A molecular single electron transistor (MSET) detector device (14) is described that comprises at least one organic molecule (87) connecting a drain electrode (84) and a source electrode (82). In use, said at least one organic molecule (87) provides a quantum confinement region. At least one analyte receptor site (90, 92) is provided in the vicinity of said at least one organic molecule (87) that bind molecules of interest (analytes). A fluid analyser (2) is also described that includes the MSET detector, a pre-concentrator (4) and a fluid gating structure (6). The fluid gating structure (6) is arranged to selectively route fluid from the pre-concentrator (4) to either one of the detector (14) and an exhaust port (12). The pre-concentrator (4), fluid gating structure (6) and detector (14) are each formed as substantially planar layers and arranged in a stack or cube.
A molecular single electron transistor (MSET) detector device comprising at least one organic molecule attached to a drain electrode and a source electrode wherein a first layer of material provides the source electrode and a second layer of material provides the drain electrode, said first and second layers are spaced apart by a third layer of substantially insulating material, where at least one of said first and second layers is comprised of a silicon semiconductor, wherein, said at least one organic molecule provides a quantum confinement region and at least one analyte receptor site is provided in the vicinity of said at least one organic molecule.
An analyser comprising a fluid analyzer and a pre-concentrator for releasably retaining analytes from a fluid including an MSET device comprised of at least one organic molecule attached to a drain electrode and a source electrode, wherein, said at least one organic molecule provides a quantum confinement region and at least one analyte receptor site is provided in the vicinity of said at least one organic molecule, wherein a shutter may be retained, without the application of power, in an open position in which fluid is routed from the pre-concentrator to the MSET device or in a closed position in which fluid is routed from the pre-concentrator to an exhaust port.
A method of chemical detection comprising the steps of:
A molecular single electron transistor (MSET) detector device comprising at least one organic molecule attached to a drain electrode and a source electrode wherein, in use, said at least one organic molecule provides a quantum confinement region wherein at least one of said source electrode and said drain electrode are formed from silicon semiconductor material and are spaced apart by a substantially insulating material, wherein at least one analyte receptor site is provided in the vicinity of said at least one organic molecule.
A method of forming a molecular single electron transistor comprising the steps of (i) forming source and drain electrodes and (ii) locating an organic molecule between said source and drain electrodes, wherein the source and drain electrodes are formed using a complementary metal oxide (CMOS) process, and wherein at least one of said source and drain electrodes are formed from silicon semiconductor and are spaced apart by a substantially insulating layer, wherein at least one analyte receptor site is provided in the vicinity of said at least one organic molecule.
