Scientists at Duke University have developed a ‘nanorattle’ system that allows for the detection of mRNA biomarkers of cancer. The tiny structures consist of gold nanospheres with a surrounding silver nanocage, forming the so-called rattle. The nanorattles are also loaded with light scattering dyes called Raman reporters. When...
