A method for depositing a film on a substrate, which includes the steps of forming a film using a liquid composition that includes a neutral surfactant and a charged lamellar compound, placing the film in contact with the substrate and depositing the film on substrate. Also, a process for analyzing a substrate onto which a film has been deposited by the method.

Method for protecting air-sensitive or evaporation-sensitive objects

A microfluidic chip comprising at least one dialysis crystallisation cell. The cell includes: a substrate made of PMMA; a first level including a tank defined at least partially by the substrate and by an outer wall of the cell, the tank being in fluid communication with a channel for inlet and a channel for outlet of a solution allowing the crystallisation method to be implemented; and a second level including a dialysis chamber defined at least partially by an inner wall of the cell without contact with the substrate and by a dialysis membrane forming an interface between the tank and the dialysis chamber, the inner wall including at least one one-piece portion in which the periphery of the membrane is kept sealed.

Microfluidic chip for the crystallisation of molecules, preparation method, device comprising said chip and method for crystallisation of molecules

A device for crystallizing a molecule to be crystallized, which includes: at least one crystallization cell that includes a crystallization chamber for receiving a first solution Scontaining the molecule to be crystallized and the crystal seeds thereof, a dialysis membrane, and a container to be filled with a second solution Sthat contains constituents selected from the group containing crystallization agents, additives and buffers; and at least one image acquisition means. The crystallization device is characterized in that it includes: at least one addition means arranged to add, to the container, constituents selected from the group containing crystallization agents, additives and buffers of solution S; and/or at least one sampling means arranged to collect, from the container, all or a portion of solution S. The invention also relates to a crystallization method.
