Abstract:
The present invention proposes a method as well as a device enabling in particular the absorption or the light diffusion of biological samples to be measured. It enables the measurement of low absorption or diffusion and can for example be applied for measuring the hybridization of DNA strands.

Abstract:
A method for concentrating particles, including: placing the particles close to and/or on at least one waveguide of a support, and injecting light radiation into the waveguide causing grouping of particles into one or plural clusters on the waveguides.
Abstract:
A method for sorting particles, including: marking the particles to modify their optical index, placing the particles on a waveguide of a support, and injecting light radiation into the waveguide, the injecting causing displacement of particles on the waveguide and separation of the particles.
Abstract:
The present invention relates to a substrate coated with a transparent organic film, to a process for the manufacture of this substrate coated with the transparent organic film and to its use. The substrate coated with a film is characterized in that the film is an electrical insulator organic polymer which is transparent in at least one wavelength range and in that the said film is combined with a label which emits at least in the said wavelength range. It has an application in particular in a means for the detection of a chemical entity, for example a biochip, in a process for the quality control, a process for the certification or a process for the authentication of an object.

Abstract:
A method for controlling directly and in real time positioning of a biological element on a zone of a support, in which the biological element is labeled with a tracer that emits a light radiation and the zone of the support is located in a layer of a material capable of trapping the light radiation. The biological element is positioned on the zone of the support. The intensity of the light radiation trapped in the layer is measured. The positioning of the biological element is determined by comparing the intensity thus measured with at least one reference value. The above operations can be carried out successively or simultaneously. A device can apply the method to the positioning of one or more biological elements on one or more zones of a support.
Abstract:
A method for separation of particles with different sizes. The method introduces radiation in a waveguide, coupled to a second guide in a coupling area, the radiation entraining all particles towards the coupling area, and separates the particles as they pass into the coupling area.
