Abstract
A reagent delivery network can include an inlet microfluidic channel, a microfluidic cross-channel branching off from the inlet microfluidic channel, a resistor positioned along the inlet microfluidic channel at a location to redirect fluid from the inlet microfluidic channel into the microfluidic cross-channel, and an outlet microfluidic channel having a side-wall opening connected to the microfluidic cross-channel. The outlet microfluidic channel can receive fluid from the microfluidic cross-channel. The microfluidic cross-channel can include a constriction region and a reagent storage chamber having reagent therein.
