After 72 hours of exposure to ambient light, strands of nanoparticles twisted and bunched together. While light has been known to affect matter on the molecular scale—bending or twisting molecules a few nanometers in size—it has not been observed causing such drastic mechanical twisting to larger particles. The nanoparticle ribbons in this study were between one and four micrometers long. (Credit: Nicholas Kotov)
U. MICHIGAN (US)—Engineers have demonstrated that light itself can twist ribbons of nanoparticles. The details are reported in the current edition of Science. Continue…
