", other researchers can have the tools and knowledge to build bio-hybrid systems, and attempt to address challenges in health, medicine and the environment that we face as a society." "We wanted to provide detailed recipes and protocols so that others can duplicate the work and further permeate the idea of 'building with biology'," says Bashir. Dubbed 'bio-bot', the walking, 6mm-long device can be powered by muscle cells, controlled with electrical and optical pulses and could one day roam your body to deliver drugs, detect disease or remove pieces of tissue.Ĭrucially for would-be bio-bot builders, the process, published in Nature Protocols, describes every fabrication step from 3D-printing a skeleton to tissue-engineering a muscle actuator, including the part numbers for every component Bashir uses in his laboratory. In March this year, American electrical engineer and scientist Professor Rashid Bashir published a blow-by-blow account of how to design and make a muscle-powered biological machine.
