SCIENCE - Programmable glue made of DNA directs tiny gel bricks to self-assemble

A team of researchers has found a way to self-assemble complex structures out of bricks smaller than a grain of salt. The new method could help solve one of the major challenges in tissue engineering: Creating injectable components that self-assemble into intricately structured, biocompatible scaffolds at an injury site to help regrow human tissues ...
