Scientists Create First 'Nano-Ear' to Listen in on Sounds of Cells

It’s a marvelous piece of nanotech innovation using gold nano-particles and an existing technology known as “optical tweezers” and it will enable scientists to eavesdrop on the private lives of bacterial cells, and even viruses, as they move about and replicate. The so-called “nano-ear” is actually an intricate system of lasers and gold nano-particles (note:
