Abstract: The present invention relates to an electrode assembly having a laminate structure comprising: a first insulating capping layer; a first conducting layer capped by the first insulating capping layer and substantially sandwiched by at least the first insulating capping layer such as to leave exposed only an electrical contact lip of the first conducting layer; and an array of etched voids extending through at least the first insulating capping layer and the first conducting layer, wherein each void is partly bound by a surface of the first conducting layer which acts as an internal submicron electrode.

Abstract: A micro electromechanical (MEMS) antenna (36) is positioned on one side of a substrate and is connected to a MEMS switch comprising a capacitor bridge (46) and to a transmission line (42) by means of a thru hole or via (48) which forms an electrically conducting path through the substrate. This arrangement provides a common ground plane for the antenna and switch and shields the switch from the electromagnetic radiation received or transmitted from the antenna. The switch may comprise a topmost metal layer which extends across a bridge structure formed by a polymer layer (19). The polymer layer comprises poly-monochloro-para-xylene (parylene-C). Homogeneous or heterogeneous antenna array structures are implemented. The antenna arrays may include one or more different type of antennas with for example different shapes, rotations and reflections.

Abstract: The present invention relates to assay assemblies, components of assay assemblies, methods of determining one or more properties of a sample liquid, and methods of making components of assay assemblies. The present invention allows the properties of very small volumes of sample liquid to be probed, by providing a first surface having at least one sample liquid wettable surface region defined by a sample liquid repelling boundary, and a second surface, opposed to the first surface, having analyte binding agent immobilised thereon.
