Abstract: A method for the detection of analytes within a fluid, said method comprising the steps of prearranging a sensorized device (100) comprising at least one SAW sensor (110), said or each SAW sensor (110) comprising a substrate (115) having an outer surface (IIS?) comprising at least one piezoelectric portion, at least one emitting interdigital transducer (111) arranged on said piezoelectric portion of said outer surface (115?), said emitting interdigital transducer (111) arranged to emit a surface acoustic wave in response to an input electric signal, at least one reflector electrode (112) arranged on said outer surface (115?), said reflector electrode (112) arranged to reflect said acoustic wave towards said emitting interdigital transducer (111).

Abstract: A device for controlling liquid motion includes a substrate (10) of material having piezoelectric properties, and a system for controlling the motion of a quantity of liquid placed in contact with the substrate. The control system includes at least one interdigitated transducer (T1, T3, T5, T7), applied to the substrate (10) and designed for selectively generating a surface acoustic wave adapted to propagate on the substrate (10) and interact with the quantity of liquid. The control system further includes an acoustic resonator (30) which is placed on the path of the surface acoustic wave, and which is adapted to normally allow the forward transmission of the surface acoustic wave having a frequency equal to a resonance frequency of the acoustic resonator, and to reflect the surface acoustic wave back towards the transducer when the quantity of liquid is present within the acoustic resonator.

Abstract: A monodose inhaler for powdered medicaments consists of a hollow substantially pipe-shaped body that has a first portion (H), for housing a capsule or cartridge of powdered medicament, defined by a wall (W) in which there are formed slots (S) as air intakes to an inner region where the powder drops, and a second portion (M) connected to the first portion (H) for delivering the medicament by means of a primary stream (F) that carries the powder from the drop region along a delivery duct (D) whose end is suitable to be placed in the patient's mouth, and it further includes a secondary duct (D?) located under the delivery duct (D) and provided with its own air intake (S?) for delivering a powderless secondary stream (F?).

Abstract: A device for controlling fluid motion in a micro/nanofluidic structure of channels by means of surface acoustic waves is described. The device comprises a structured volume of material bearing a predetermined configuration of micro/nanofluidic channels for holding and transferring amounts of fluids adapted to define at least one fluid inlet and at least one fluid outlet and presenting a hydrophobic behaviour for the fluids to be handled and a substrate made of material with piezoelectric properties coupled to the micro/nanofluidic channels.

Abstract: Herein described is a device for controlling fluid motion in a micro/nanofluidic structure of channels, comprising: a structured volume of material (30), bearing a predetermined configuration of micro/nanofluidic channels (C) for holding and transferring amounts of fluids, adapted to define at least one fluid inlet (IN) and at least one fluid outlet (OUT), and presenting a hydrophobic behaviour for the fluids to be handled; and a substrate (31) made of material with piezoelectric properties, coupled to the abovementioned configuration of micro/nanofluidic channels, bearing means for active control of the motion of an amount of fluid, including transducer means (T1-T6) which comprise at least one pair of interdigitated electrodes applied on the substrate (31), which are arranged to selectively generate a surface acoustic wave adapted to propagate on the substrate (31) and interact with the amount of fluid.

Abstract: A monodose disposable inhaling device is disclosed which is suitable for delivery, via the respiratory tract, therapeutic medication, which includes among its objects and advantages increased convenience in medication with dry medicaments in powder form, especially with respect to accuracy of dosage and accurate placement of the drug. In one embodiment the inhaler device generally consists of a body member having a delivery portion constructed integral with a housing portion, a button member, a spring member and a spring and capsule support member. Additionally, a screen member can be disposed within the body member at the intersection of the delivery portion and the housing portion.
