My friend and colleague, Dr. Charles Sykes of Tufts University, recently sent me a link to an interesting video his research group has put together! Dr. Sykes' group has been studying the behavior of complex molecules on surfaces at low temperatures. They use scanning tunneling microscopy to image and interact with the molecules on the surface, with the ultimate goal of making nanoscale machines, i.e. machines consisting of a single molecule!
Their research video describes the techniques, science, and challenges in developing such molecular motors:
Let me know what you think of the video, or contact the Sykes group directly!
