Abstract

An easy and versatile approach to construct DNA hydrogels is reported. The DNA building blocks, a Y-scaffold and a linker, can self-assemble into DNA hydrogels by the hybridization of their “sticky ends”. It is shown that the DNA hydrogels undergo a sol-gel transition upon heat or enzymatic treatment, and these responsiveness can be adjusted by tailoring the sequence of the building blocks.
