Abstract: A chip for biochemical reactions comprising: a first body including a plurality of first through openings arranged according to an arrangement pattern; a second body, having a hydrophilic surface, coupled to the first body on the hydrophilic surface; and an intermediate layer, which extends over the hydrophilic surface and forms a coupling interface between the first and the second bodies. The intermediate layer is of hydrophobic material, extends continuously over the hydrophilic surface, and has a plurality of second through openings through which respective regions of the hydrophilic surface are exposed. The hydrophilic regions may be functionalized for carrying out a PCR.

Abstract: A device such as a dosimeter for detecting ionizing radiation, for example, X-ray radiation, in hospitals or the like. The device includes scintillator material configured to produce light as a result of radiation interacting with the scintillator material, and photoelectric conversion circuitry optically coupled to the scintillator material and configured to produce electrical signals via photoelectric conversion of light produced by the scintillator material. The device includes a plurality of photoelectric converters optically coupled with the scintillator material at spatially separated locations. The plurality of photoelectric converters thus produce respective electrical signals by photoelectric conversion of light produced by the scintillator material as a result of radiation interacting with the scintillator material. Improved energy linearity is thus facilitated while providing more efficient detection over the whole energy spectrum of radiation detected.

Abstract: A radiation scintillator detector comprising a substrate on which are arranged a scintillator module and a silicon photomultiplier optically coupled one to the other. The detector includes a package comprising an outer casing enclosing said scintillator module and said photomultiplier, said package comprising inside said outer casing an inner casing comprising resin reflecting photons, in particular infrared and/or visible photons, emitted by said scintillator module upon receiving a ionizing radiation, enclosing said scintillator module and said photomultiplier.
