The research group of Professor Seiya Kobatake of the Osaka City University Graduate School of Engineering (Applied Chemistry and Bioengineering Department) has discovered a microcrystal that twists when exposed to light. This discovery opens up the possibility in the near future to develop microscopic mechanical devices that can be driven by light, as light energy is converted into mechanical energy. The research has been published in the online edition of ‘Angewandte Chemie International Edition' (published from 19 July). ???
