Abstract: Method for preparing a homogeneous collagen-based material by concentration of a collagen solution, includes bringing a collagen solution into contact by way of continuous injection and use of the material for tissue repair.

Abstract: The invention relates to a method for determining the maximum open circuit voltage and the power that can be output by a photoconverter material subject to a measurement light intensity, the method including the following steps: measuring the photoluminescent intensity of the material, measuring the absorption rate of the photoconverter material at a second wavelength substantially equal to the photoluminescent wavelength of the photoconverter material, determining the maximum open circuit voltage of the photoconverter material with the measurement light intensity by means of the absorption rate and the photoluminescent intensity measured at substantially the same wavelength; said invention being characterised in that the light source and the photoconverter material are arranged such that the angular distributions of the rays incident on and emitted by the lit surface of the material and collected by the detector are substantially identical.

Abstract: The present invention relates to a method for producing platelets from mature megakaryocytes. More particularly, the invention relates to an ex vivo method for producing platelets, from mature megakaryocytes, said method comprising a step of subjecting a suspension of mature megakaryocytes to a flow having a minimal shear rate of 600 s?1 on a solid phase coated with Von Willebrand factor.

Abstract: The present invention relates to a method for preparing an MOF solid of a crystallised and porous aluminium aromatic azocarboxylate, in a non-aqueous organic medium. The invention also relates to solids made up of metal-organic frameworks (MOF) of aluminium aromatic azocarboxylates capable of being obtained by the method of the invention, as well as to the uses thereof for the storage of liquid or gaseous molecules, for selective separation of gas and for catalysis.

Abstract: The invention relates to solid organometallic hybrids with modified surface. Said solid may be used for example for the encapsulation and vectoring of molecules of interest such as active pharmaceutical agents, compounds of interest in cosmetics and markers, for example, contrast agents. Said solids show good results in terms of loading capacity in medicament agents and in biocompatibility.

Abstract: The invention relates to nanoparticles made from organometallic hybrid materials made from iron carboxylates, used for example as contrast agents. The particles can also be used for the encapsulation and vectoring of molecules of interest such as active3 pharmaceutical agents, cosmetically interesting compounds and markers. Apart from the intrinsic properties thereof for imaging, said nanoparticles give good results in terms of capacity for loading with medicaments and in biocompatibility.

Abstract: An improved biochip type device comprising a substrate (10) including an intermediate non-absorbent multilayer mirror (12) covered by a layer (14) of high refractive index material having chromophore elements (16) fixed thereon, the layer (14) further including feature (24) for extracting guided-mode light in order to recover the light emitted by the chromophore elements (16) into the layer (14) in response to light excitation, and direct the light to detection and measurement means.
