Abstract: The present invention relates to a novel microwaveable food cover device. The device is a food-safe, microwaveable container with a water supply for preventing dehydration of food as it is heated. The microwaveable food cover device comprises a body component for covering a user's food while in the microwave. The body component comprises a plurality of through-holes to allow moisture inside the cover. Further, a water cup is secured to the side of the body component which is filled with water during use to create moisture. Users can pour water into the cup attached to the side of the body component. The water adds moisture to the food via the plurality of through-holes to prevent heat from drying it up. The device can also help prevent food splatter to keep a microwave clean.

Abstract: 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.
