Nanowire Wrapping a Beam of Light around a Human Hair

The nanotechnology research field is pretty fertile these days. Researchers at Harvard recently showed a nanowire which could be the next big diagnostic tool for doctors. Meanwhile, University of Southern California scientists have developed a 'nanosensor' that only works when noise is added. And another Harvard team has developed nanoscale fibers that are thinner than the wavelengths of light they carry which may have applications in ever-shrinking medical products and tiny photonics equipment such as nanoscale laser systems, tools for communications and sensors. This news roundup contains more details and references about these projects. You'll also find a stunning picture of a s ilica nanowire wrapping a beam of light around a strand of human hair.
