Which consequence results when a microfluidic device operating isothermally experiences a blockage, exceeding critical capillary backpressure during droplet generation?

💡 Explanation

Reversed phase wetting occurs because increased backpressure surpassing the capillary limit causes fluid to preferentially wet the nozzle material rather than forming droplets; therefore, the intended droplet generation stalls due to increased adhesion, rather than mere flow impedance.
