  • Microfluidic chip for the crystallisation of molecules, preparation method, device comprising said chip and method for crystallisation of molecules
    Patent number: 11174568
    Abstract: 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.
    Type: Grant

  • Crystallization of chemical species/polymorphs and microfluidic apparatus and screening methodology therefor
    Patent number: 8053242
    Abstract: The crystallization of chemical species/polymorphs comprises forming droplets of a solution of a substance with optionally different concentrations of said substance in an inert phase; producing and storing the droplets in at least one storage microchannel (1); forming crystals in all droplets; increasing the temperature in order to induce the dissolution of at least a portion of the crystals in at least some droplets; and analyzing the crystallization and dissolution process.
