Thermoresponsive poly(ether urethane) bioink

PoloxInk

Temperature-triggered gelation for extrusion bioprinting and payload delivery.

Detailed specifications
CompositionP407-derived poly(ether urethane), CHP407/NHP407
GelationSol-to-gel transition on warming; concentration tunes gelation temperature and kinetics
CrosslinkingTemperature-triggered; no chemical crosslinkers, solvents, catalysts or UV curing required
Reported extrusion conditions15% w/v at 25 °C through G27 nozzles; 70–100 kPa
Reported gelation timeLess than 5 minutes at 37 °C
Fluid stabilityHigher stability than corresponding native Poloxamer 407 formulations, as reported in the catalogue
Ready-to-use formatSterile 3 and 5 mL cartridges; compatibility with the selected bioprinter to be confirmed
Other formatsPowder for custom formulations; custom formats on request
