  • Device and method for standardizing myoblast differentiation into myotubes
    Patent number: 10711248
    Abstract: A method and device for standardizing myoblast differentiation into myotubes, including a substrate (1) and at least one cell-adhesive pattern (2) for culturing myoblasts on the substrate. The pattern (2) has an elongated surface. A central region (2C) and two lateral regions (2L) extend from the central region in both directions along a longitudinal axis of the pattern. The ratio between the maximum width (WC) of the central region (2C) and the maximum width (WL) of the lateral regions (2L) is greater than or equal to 2. The ratio between the length (L) and the maximum width (WC) of the pattern (2) is less than or equal to 4. The method includes providing a device as described above, depositing myoblasts on at least one cell-adhesive pattern of the device, culturing the myoblasts in a differentiation medium to promote cell differentiation into myotubes and constrain elongation of the myotubes.

  • Object separation device using optical method
    Patent number: 7511263
    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.
