Abstract: A method and device, based on a film of a luminescent substance, such as colloidal semiconductor nanocrystals dispersed in a polymer matrix, for conducting quantitative and real-time analyses of PCR processes or of biomolecular interactions in genomics and/or proteomics. The optical detection system is based on FRET processes between the luminescent substance (which acts as the donor in the FRET process) and a suitable fluorophore (which acts as the acceptor species) with which the DNA or other biomolecule is marked. The device is essentially composed of a reaction microchamber with a wall formed by a thin film made of polymer material, in which the nanocrystals are uniformly dispersed, or made of a photoluminescent or electroluminescent polymer. Molecular probes are chemically immobilized on the surface of the polymer film for the specific recognition of the analyte which is to be determined in real time.

Abstract: Optical system for detecting the concentration of combustion products operating in situ and at high temperature based on measurement of the optical absorption of a gaseous mixture of combustion products through a photodetecting sensor based on gallium nitride (GaN), aluminium nitride (AlN), indium nitride (InN) and corresponding alloys. The operating temperature of the sensor preferably lies between 500° C. and 700° C., but the resistance of the active material permits use at even higher temperatures. This system can be used to measure the concentration of chemical species present in combustion products directly at their outlet, where the high operating temperature makes it possible to avoid fouling of the sensor caused by carbonaceous and non-carbonaceous deposits. The rate of response of the system is less than or equal to 1 millisecond and makes it possible to adjust the parameters of an associated combustion process control system in real time.

Abstract: An electroactive photonic device (D) comprises a substrate (1), at least one cathode layer (2), at least one anode layer (4), and at least one layer of active material (3) based on organic compounds and interposed at least partially between the anode and cathode layers (2, 4). The layers (2, 3, 4) are arranged on the substrate (1) in a predetermined configuration such that the device (D) can convert luminous energy into electrical energy or vice versa. The substrate (1) is made of float glass.

Abstract: Masters for imprint processes are produced by providing a resist layer, and patterning the resist layer after a respective mold pattern to produce a patterned resist layer adapted to be directly used as a master for imprint lithography. Preferably the resist is spin cast on a substrate and is comprised of a photoresist, such as negative-tone, electron-beam sensitive resist having a glass transition temperature above 200° C. and adapted to be mechanically stable to pressures up to 104 psi. Preferably, the resist is a polymer resist, such as an epoxy resist e.g. SU8 and SU8-2000. Patterning the resist layer includes the steps of structuring the resist layer, soft-baking the structured resist layer in order to selectively cross-link the structured portion of the structured resist layer and developing the structured resist layer in order to receive a patterned resist layer. The patterned resist layer is preferably cured e.g.

Abstract: Thiophene oligomers which are excitable in the visible and ultraviolet region and each having at least one functional group able to form a covalent bond with organic and/or biological molecules, so as not to alter either the fluorescence properties of the oligomers or the biological activity of the bound molecules, and their use as fluorescent markers in analysis techniques.

Abstract: A luminescent organic material for light-emitting devices, in particular, for organic LEDs, having at least one thienyl-S,S-dioxide unit obtained by functionalizing the sulfur of a thiophene ring. Inserting a thiophene ring functionalized with oxygen atoms in oligothiophenes of appropriate length and symmetry provides for maintaining or increasing intrinsic quantum efficiency and for modulating the wavelength of the emitted light.
