  • Patent number: 11297828
    Abstract: Methods and devices for lyo-processing biological materials are provided. The methods include submerging the biological molecules or cells in a buffer solution comprising trehalose, withdrawing the biological molecules or cells from the buffer solution in an environment that does not include oxygen to generate lyo-stabilized biological molecules or cells, and storing the lyo-stabilized biological molecules or cells. The devices include a motor that lowers a horizontal member having a clamp for receiving a substrate toward a solvent reservoir and raises the horizontal member having the clamp up and away from the solvent reservoir.

  • Patent number: 10568318
    Abstract: Disclosed are devices and methods for non-cryogenic vitrification of biological materials that include the steps of providing one or more capillary channels of which a first opening is operably in contact with a moisture containing vitrification mixture made of a biological material and a vitrification agent. The capillary absorbs and transports the moisture to the second opening through capillary action, and the moisture is subsequently evaporated into a surrounding low humidity atmosphere until the vitrification mixture enters into a vitrified state.

  • Publication number: 20090288479
    Abstract: The present invention provides standing wave fluidic and biological tools, including: at least one elongated fiber that has mesoscale (i.e. milliscale), microscale, nanoscale, or picoscale dimensions, the at least one elongated fiber having a first end and a second end; and an actuator coupled to the first end of the at least one elongated fiber, wherein the actuator is operable for applying oscillation cycles to the at least one elongated fiber in one or more directions, and wherein the actuator is operable for generating a standing wave in the at least one elongated fiber. These standing wave fluidic and biological tools are selectively disposed in a fluid to provide a function such as mixing the fluid, measuring the viscosity of the fluid, attracting particles in the fluid, shepherding particles in the fluid, providing propulsive force in the fluid, pumping the fluid, dispensing the fluid, sensing particles in the fluid, and detecting particles in the fluid, among others.
