Abstract: A device (100) for measuring a concentration of NO in exhaled air is provided. The device (100) comprises a mouthpiece (11), an NO sensor (12), an airway obstruction measurement and an analysis module. The mouthpiece (11) receives the exhaled air during an exhalation. The NO sensor (12) measures the concentration of NO in the exhaled air. The airway obstruction measurement module determines an airway obstruction parameter. The analysis module (16) analyzes an inflammatory status of a respiratory system based on a combination of the measured concentration of NO and the determined airway obstruction parameter.

Abstract: The invention relates to the use of an organic semi-conducting compound for detecting NO, as well as a sensor (18) and device (9) wherein such a compound is used for the detection of NO. The device (9) allows the respiratory gas analysis in a simple, non-invasive way, which can be used to predict the condition and/or function of the lungs and respiratory ducts. The sensor (18) is more specifically from the nanoscale FET type structure.

Abstract: The present invention relates to the use of the optical properties of nanowires (1) for biomolecule (2) detection. The advantages of using nanowires (1) are a high specific surface area (1a) to bind receptor molecules (3) and size dependent optical properties because of strong quantum confinement of the carriers, i.e. nanowires (1) with different diameters show different colours. The proposed transduction mechanism is based on energy transfer between the biomolecule (2) and the nanowire (1) (or vice versa). Preferably, the target biomolecule (2) is a luminescent biomolecule (2), or said biomolecule (2) is labelled with a dye for quenching of the luminescence of the nanowire (1).

Abstract: This invention relates to a method of manufacturing an field emission electrode, including a field emission electrode substrate (1) and a plurality of emitter particles (2) arranged on said field emission electrode substrate (1), comprising the steps of:—dispersing said emitter particles (2) as aerosolized emitter particles (2) in a carrier gas stream;—electrically charging said emitter particles (2); and—directing said charged emitter particles (2) in the carrier gas stream via at least one outlet towards the field emission electrode substrate (1) while maintaining an electric field between the substrate (1) and a deposition electrode (10) near the outlet, whereafter said emitter particles (2) are deposited on and adhered to said field emission electrode substrate (1).

Abstract: A field emission device (1) may be used for emitting electrons in, for example, a field emission display (FED). Field emission tips (40) are used for the emitting of electrons in the field emission device (1). In operation of the field emission device (1) a voltage is applied between a first electrode (4) having electrical contact with the field emission tip (40) and a second electrode (34) to make the field emission tip (40) emit electrons. To form a field emission tip (40) a layer of liquid material is applied on a substrate (2) provided with the first electrode (4). The layer of liquid material is embossed with a patterned stamp and subsequently cured to form a field emission tip structure (20). A conductive film (38) is applied on the field emission tip structure (20) to form a field emission tip (40) that has electrical contact with the first electrode (4).

Abstract: A field emission device (100) is provided with a cathode electrode (120) and a gate electrode (140). Between these electrodes, a patterned dielectric layer (130) is provided. According to the invention, this dielectric layer (130) is manufactured from a liquid precursor material (131) which is patterned by means of a liquid embossing step, i.e. engaging a patterned stamp (150) with the liquid material (131). After removing the stamp (150), the liquid material is cured to form the patterned dielectric layer (130). Preferably, in a subsequent manufacturing step, the cathode electrode (120) or the gate electrode (140) is formed over the patterned dielectric layer (130) in a self-aligned way.
