Another intriguing feature of the intermittent flow regime is the production of micro-rods. Nearly all published methods of manufacturing or fabricating hydrogel micro-particles via microfluidics use two phases, typically a waterin-oil emulsion . In these, the oil phase serves as a suspending fluid to create monodisperse droplets or to control the location and rate of crosslinking. Premature crosslinking often causes clogging and device failure, and thus is avoided in these contexts . By contrast, we have identified a scheme where clogging is controllable without an oil phase, so that the resulting micro-rods are produced using only the aqueous phase. This singlephase procedure greatly simplifies the washing and separation of particles after production. The rods are stable in solution and sufficiently robust to maintain their shape upon pipetting. The diversity of chemical and physical conditions, represented in the intermittent region of the flow phase diagram, may allow for tuning both the size and stiffness of the gel rods, which are important features in many applications . The rods maintain their shape after ablation, with widths equal to the channel width. This suggests channel geometry dictates their width. Additionally, there is potential to tune the stiffness of the micro-rods by preparing them at different reaction conditions. Further characterization of gels in all areas of the flow phase diagram could describe this tunability.
