Abstract: A delivery device for delivering a metered amount of substance (L) in response to exhalation by a user, the delivery device comprising: a mouthpiece (5) through which the user in use exhales; an outlet (45) from which substance Is delivered; and a dispensing unit (35) which is operable to dispense a metered amount of substance through the outlet in response to exhalation by the user through the mouthpiece, wherein the dispensing unit comprises a body member (37) which includes a cavity (39) for containing a metered amount of substance, an outlet nozzle (43) which is fluidly connected to the cavity from which substance is in use delivered, and a dispensing (41) member which is movably disposed in the cavity and configured to be driven through the cavity by a driving pressure created by exhalation of the user, such as to cause substance to be delivered from the outlet nozzle.

Abstract: A method for fabrication of a lab-on-a-chip system makes use of first and second mold parts, which are adapted to join each other to form a cavity to accommodate a positioning means and a support structure. The method includes receiving the chip in the positioning means, forming the cavity by joining the first and second mold parts, securing the chip with a fluid port of the chip to rest on the support structure for the support structure to mask the fluid port, introducing a molding material into the cavity to over-mold at least part of the chip and a volume extending away from the chip, separating the first and second mold parts, and extracting the chip from the mold. A fluid channel is formed by the support structure.

Abstract: Polybranched organic/inorganic hybrid polymer and method for its manufacture. The hybrid polymer has the form of an inorganic core carrying organic branches. The core is first prepared by controlled hydrolysis and condensation of a silane with a structure: X—B—Si(—Y)3 in which X?NP1R2, while R1, R2 are chosen among hydrogen, alkyl and aryl, or R1, R2 are chosen among condensation products, addition products of one or more type of chemical substances such as acids, alcohols, phenols, amines, aldehydes or epoxides. B is a linkage group chosen among alkylene and arylene which may include oxygen, nitrogen, sulphur, phosphorous, silicon and boron. Y is chosen among hydrolyzable residues such as alkoxy, carboxyl, and halogen. The organic branches are developed by substituting N—H hydrogen atoms in the X—B group by reactions that are typical for primary and secondary amines, and/or by adding an acid that causes an addition to the N atoms of the X—B group in the core.
