Abstract: A method for detecting and quantifying additives in a complex aqueous fluid, and a method for detecting an inhibitor of mineral deposition or corrosion, injected in a gas or oil well. The invention also relates to a developer solution including a lanthanide and a chelating agent for detecting said additives or inhibitors.

Abstract: A ligand of Formula (A): or a carboxylate salt thereof; wherein Y1, Y2 and Y3 each independently represents —COOH or a picolinate of Formula (i): wherein each R1 independently represents a chromophore group; L1, L2 and L3 each independently represents a single bond or a linker; and X1, X2 and X3 each independently represents a hydrogen atom, a coupling function or a bio-vectorizing group. Also, a process for manufacturing the ligand and to a process for manufacturing a chelate by complexation by the ligand of a rare-earth cation, preferably a lanthanide cation. Further, a use of the ligand and/or the chelate in biological imaging and/or photoluminescence imaging.

Abstract: The invention relates to a method suitable for detecting, capturing and/or selectively releasing chemical elements selected from poor metals, alkalines, alkaline earths, actinides and rare earths. Said method involves a molecular assembly formed by at least one amine, and at least one aldehyde and/or an imine and/or CO2, or an adduct formed by the contact between an amine and CO2, and at least one of said chemical elements. The invention also relates to a kit for implementing said method for detection, capture and/or release.

Abstract: A method of embolizing an area of treatment includes providing a composition that includes a radiopaque, non-biodegradable, water-insoluble iodinated benzyl ether of poly(vinyl alcohol) consisting of a poly(vinyl alcohol) (PVA) having covalently grafted thereon iodinated benzyl groups comprising from 1 to 4 iodine atoms per benzyl group as the only substituents wherein a grafted repeating unit has formula (I) wherein n is from 1 to 4: and introducing the composition into the area of treatment.

Abstract: A method for in vitro diagnosis of Staphylococcus aureus producing Panton-Valentine Leukocidin (PVL), using a biological sample derived from an individual liable to be colonized by or infected with Staphylococcus aureus, wherein the diagnosis is carried out by detection of PVL using a routine immunological test, and the biological sample is pretreated in order to denature the PVL.

Abstract: The present invention relates to materials and particularly “organometallic-organic-inorganic hybrid materials” that can be used as heterogeneous catalysts for selective catalytic reactions. More precisely this invention relates to organic-inorganic hybrid nanostructured materials comprising a regularly distributed stabilized carbene that binds strongly to a metal so as to form a stable organometallic-organic-inorganic hybrid material having high catalytic performances.

Abstract: The present invention relates to a non covalent molecular structure comprising a carbon nanostructure and a pyrene based glycoconjugate (I) which is linked to the said carbon nanostructure by a non covalent link, the said glycoconjugate (I) having the formula: wherein B is a group which is present on any of the ten carbon atoms of the pyrene structure represented in (I) susceptible to bear a substituent, and is represented by the following group: —(CH2)n-CO—NH-A, wherein n is an integer from 1 to 9, A is a group of formula: The present invention also relates to an electronic device comprising the said non covalent molecular structure, and to the use of this device for the detection of a lectin involved in bacterial or viral infections. Thus the invention also relates to a method for detecting the presence of a lectin in a sample to be analysed.

Abstract: The present invention relates to a non covalent molecular structure comprising a carbon nanostructure and a porphyrin based glycoconjugate (I) which is linked to the said carbon nanostructure by a non covalent link, the said glycoconjugate (I) having the formula (I): wherein M is a metal selected in the group comprising Fe, Ni, Zn, Cu, Mn, Cr or Co, B is a group which is present on at least one of the four phenyl group (C6H5) represented in (I), n is an integer from 1 to 3, that is to say that one to three B group(s) may be present on each phenyl group, and B is represented by a -A-C group wherein A is selected in the group comprising an oxygen atom, a sulfur atom, a NH group or a (CH2)n1 group, n1 being an integer from 1 to 10, C is a group of formula (II). The present invention also relates to an electronic device comprising the said non covalent molecular structure, and to the use of this device for the detection of a lectin involved in bacterial or viral infections.

Abstract: The present invention relates to a method for in vitro diagnosis of Staphylococcus aureus producing Panton-Valentine Leukocidin (PVL), using a biological sample derived from an individual liable to be colonized by or infected with Staphylococcus aureus, wherein the diagnosis is carried out by detection of PVL using a routine immunological test, characterized in that said biological sample is pretreated in order to denature the PVL.
