Abstract: The disclosure provides methods and compositions useful for labeling of target molecules with origin-specific nucleic acid identifiers (for example, barcodes), which can be used subsequently to identify, quantify, or otherwise characterize a feature or activity of target molecules originating from a particular discreet volume. Such target molecules can include polypeptides expressed by cells, in which nucleic acid molecules encoding the polypeptides are labeled with the same, or matched, origin-specific nucleic acid identifiers.

Abstract: The present disclosure relates to novel compositions of additives that result from mixing at least two thermoassociative and exchangeable copolymers and at least one compound for controlling the association of these two copolymers. A lubricant composition results from mixing at least one lubricating base oil, at least two thermoassociative and exchangeable copolymers and at least one compound for controlling the association of these two copolymers. The present disclosure also relates to a process for modulating the viscosity of a lubricant composition that results from mixing at least one lubricating base oil, at least two thermoassociative and exchangeable copolymers; as well as the use of a diol compound for modulating the viscosity of a lubricant composition.

The invention relates, moreover, to kits for preparing the composition, to a thermoset-resin-based object obtained from a composition of the invention, to a process for manufacturing objects, to a process for hot-deformation of objects and to various possible uses of the compositions and objects of the invention.

Abstract: A device for optically detecting in transmission nanoparticles moving in a fluid sample includes a light source for emitting a spatially incoherent beam for illuminating the sample; an imaging optical system; and a two-dimensional optical detector. The imaging optical system includes a microscope objective. The two-dimensional optical detector includes a detection plane conjugated with an object focal plane of the microscope objective by said imaging optical system. The two-dimensional optical detector allows a sequence of images of an analysis volume of the sample to be acquired, each image resulting from optical interferences between the illuminating beam incident on the sample and the beams scattered by each of the nanoparticles present in the analysis volume during a preset duration shorter than one millisecond.
