Abstract: The present invention pertains to a sensor, suitable for use in the detection of an analyte in a fluid, comprising: a tube (4) defining a flow path for the fluid; a generally planar member (3) mounted in the flow path (?) such that the plane is in the direction of flow, wherein the member has, bound thereto, a ligand that interacts with the analyte, wherein interaction causes the member to flex; and means (1, 2) for the detection of the flexing.

Abstract: The invention is directed to a method of manufacturing single-walled carbon nanotubes comprising the steps of providing on a substrate at least one pillar comprising alternate layers of a first precursor material comprising fullerene molecules and a second precursor material comprising a catalyst, and heating the at least one pillar. It further is directed to a precursor arrangement for manufacturing single-walled carbon nanotubes comprising on a substrate at least one pillar comprising alternate layers of a first precursor material comprising fullerene molecules and a second precursor material comprising a catalyst. A third aspect is a nanotube arrangement comprising a substrate and thereupon at least one crystal comprising a bundle of single-walled carbon nanotubes with essentially identical orientation and structure.

Abstract: The present invention pertains to a sensor, suitable for use in the detection of an analyte in a fluid, comprising: a tube (4) defining a flow path for the fluid; a generally planar member (3) mounted in the flow path (→) such that the plane is in the direction of flow, wherein the member has, bound thereto, a ligand that interacts with the analyte, wherein interaction causes the member to flex; and means (1, 2) for the detection of the flexing.

Abstract: The invention provides an apparatus and a method for defining a pattern on a substrate using a shadow masking technique. Said apparatus comprises a flexible member having a movable portion and at least one aperture. The flexible member is positioned in operation above the substrate thereby acting as a shadow mask. The apparatus further comprises a support for the substrate, distance-controlling means for controlling the distance between said movable portion and said substrate, and an actuator for moving the flexible member and substrate relative to each other parallel to a surface of the substrate. The apparatus further comprises an emission source which emits materials, electrons or light and which aims through the shadow mask at the substrate where the pattern is defined. Such a pattern might be employed in micromechanic, microoptic or microelectronic devices, for example. The described apparatus may be implemented using the AFM principal.

Abstract: A field effect transistor and a piezoelectric sensor are positioned between layers of silicon and aluminum to function as a bimetallic electromechanical transducer. The transducer can be used in atomic force microscopy or as an actuator, a chemical sensor, or an oscillator.
