  • Patent number: 11430279
    Abstract: A microfluidic platform and method are provided. The microfluidic platform includes a base having an outer surface and a plurality of wells formed in the outer surface thereof for receiving fluid therein. The plurality of wells are in fluid communication with each other. A lid includes a plurality of channels having corresponding inputs and outputs. The lid is moveable between a first position wherein the lid is disengaged from the base and a second position wherein the inputs of each channel communicate with corresponding wells in the base. The fluid in each well is drawn into corresponding channels through the inputs thereof by capillary action.

  • Patent number: 10094820
    Abstract: A microfluidic device and method is provided for handheld diagnostics and assays. A first substance is frozen in a cryopreservation fluid in a first well of a lid. The lid includes a first surface communicating with a first port of the first well and a second surface communicating with a second port of the first well. A porous membrane is affixed to the first surface so as to overlap the first port and a non-porous membrane is affixed to the second surface so as to overlap the second port. The first substance may be dialytically freed from the cryopreservation fluid at a user desired time. Thereafter, the lid may be moved from a first position wherein the lid is spaced from a base to a second position wherein the lid is adjacent the channel in the base such that the first substance communicates with the input of the channel.
