    摘要: According to the invention, generally, a method for making a microfluidic aliquoting (MA) chip, adapted to fit in a Petri dish, has a center well (inlet) connected by branched channels to a plurality of side wells (outlets). The chip comes in various types, including a bMA Chip T1, bMA Chip T2, bMA Chip T3, and an rMA Chip. The branched channel improvement provides for a greater distance between neighboring channels and a decreased density near the center well. Design improvements including an injection mold design for an insert and a base and a multiplex hole punch allow for rapid fabrication of the MA chip.

    摘要: A multi-well plate comprising: inlet wells configured to contain liquid; walled observation windows located between the inlet wells, each observation window being associated with a respective inlet well; detection wells, each being disposed below a respective observation window and being associated with the respective inlet well associated with the respective observation window; outlet wells located between the inlet wells and the observation windows, each outlet well being associated with a respective inlet well and a respective detection well; inlet channels, disposed in first groups, each first group providing fluid communication between an inlet well and a respective detection well; outlet channels, disposed in second groups, each second group providing fluid communication between a detection well and a respective outlet well. The inlet channels are configured to prevent passage of the liquid from the inlet wells to the respective detection wells if no external force is applied to the liquid.
