Roland Piquepaille writes "Ohio University physicists have used a simple molecule of chlorophyll taken from spinach to develop a complex nanobiological switch. They used a scanning tunneling microscope (STM) to image chlorophyll-a and then injected it with a single electron to manipulate the molecule into four positions. The researchers say this biological switch might be used in future applications for green energy, technology and medicine. Read more for additional pictures and references about this spinach-based biological switch."
