3D printed nanomachines based on cyclodextrins
31 July, 2017
Science Daily and other scientific internet portals reported on novel nanomachines able to convert chemical energy into mechanical work (lifting a coin) through solvent exchange.
Angewandte Chemie published the work of Ke’s group on the design and synthesis of polypseudorotaxane hydrogels, which are composed of α-cyclodextrins and poly(ethylene oxide)–poly(propylene oxide)–poly(ethylene oxide) (PEO-PPO-PEO) triblock copolymers, and their subsequent fabrication into polyrotaxane-based lattice cubes by 3D printing followed by post-printing polymerization. Ke was post-doc fellow in the laboratory of Fraser Stoddarth, awarded by Nobel Prize in 2016 for similar structures.
