    The use of a split intein enables the hydrogel to be conditionally formed in response to the mixing of two liquid-phase components. Specifically, the split intein covalently links two liquid-phase building blocks via a trans-splicing reaction, yielding a polypeptide unit flanked by crosslinking units that in turn self assembles into a hydrogel. The mixing-induced formation of the hydrogel bypasses technical …
