RT Journal Article SR Electronic T1 Synthesis of cell-laden alginate microgels with tunable compositions based on microfluidic pico-injection technique JF bioRxiv FD Cold Spring Harbor Laboratory SP 2022.01.09.475570 DO 10.1101/2022.01.09.475570 A1 Yizhe Zhang A1 Angelo Mao A1 David J.

Weitz YR 2022 UL http://biorxiv.org/content/early/2022/01/11/2022.01.09.475570.abstract AB 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.Competing Interest StatementThe authors have declared no competing interest.
