We report a microfluidic pico-injection-based approach for reliably generating monodisperse cell-laden alginate microgels whose composition can be tuned in situ through modulation of the cross-linker concentration. Separating the gelation from emulsification allows for a better control over the microgel size with a microfluidic drop-maker, and an instant adjustment of the microgel composition with a pico-injector.
