Interestingly, higher Q T than that shown in Fig. may extend the range of intermittency. We observe intermittent behavior at C Alg = 10 mg/mL, C Ca 2+ = 20 mM when Q T is increased to Q T = 6µL/min (SI Fig. ). This same composition, C Alg = 10 mg/mL and C Ca 2+ = 20 mM, lies well within the red, clogging regime in Fig. , obtained at Q T = 1.2µL/min.
