Injectable PDN for microfluidics. a) Schematics showing the delivery of PDNs to microfluidic channels through injection. b) Perfusion of media through injected hydrogels. c) Confocal images showing live/dead cells within PDNs with and without perfusion after 24 h. d) Cell viability. e) PDN‐enabled microfluidic setup within a standard 6‐well plate. f) Different channels can be connected and perfused simultaneously. g) Injected PDNs can be taken out from the microfluidic channels and handled easily without rupture. **** represents P < 0.0001, n.s. represents P ≥ 0.05.
