Abstract
Described is a microfluidic serial dilution platform based well-plate using an oil-free immiscible phase driven by manual or electronic pipettors. The well-plate includes a plurality of fluidic traps, a plurality of hydrophilic capillary constriction channels and a plurality of bypass channels. Each of the plurality of bypass channels is associated with one of the plurality of fluidic traps, each of the plurality of hydrophilic capillary constriction channels is associated with one of the plurality of fluidic traps, and each of the plurality of fluidic traps is associated with one of the plurality of bypass channels and one of the plurality of hydrophilic capillary constriction channels. The well-plate further includes an inlet, an outlet, and a main channel with a plurality of portions that connects the inlet to the plurality of fluidic traps, associated hydrophilic capillary constriction channels and associated bypass channels, and the outlet.
