A molecular single electron transistor (MSET) detector device () is described that comprises at least one organic molecule () connecting a drain electrode () and a source electrode (). In use, said at least one organic molecule () provides a quantum confinement region. At least one analyte receptor site () is provided in the vicinity of said at least one organic molecule () that bind molecules of interest (analytes). A fluid analyser () is also described that includes the MSET detector, a pre-concentrator () and a fluid gating structure (). The fluid gating structure () is arranged to selectively route fluid from the pre-concentrator () to either one of the detector () and an exhaust port (). The pre-concentrator (), fluid gating structure () and detector () are each formed as substantially planar layers and arranged in a stack or cube.
