Abstract
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.
