Something unexpected happened when scientists at the University of California, Riverside, started stringing together nanoparticles of gold.
The gold wasn’t golden anymore. It changed colors.
“When we see these gold particles aggregate, we find out they have very, very beautiful blue colors,” chemist Yadong Yin told The Atlantic. That bright blue would dissipate like a sunset — morphing into purple, then red — when scientists warped the strings, breaking apart the nanoparticles
The finding was one of those happy scientific accidents that turns into something bigger. “So after we found out the reason why they show blue colors and what the structure was, then we started to think what kind of use they could have,” Yin said Read more…
