Tiny light-up barcodes identify molecules by their twinkling

An imaging technique developed at Duke University could make it possible to peer inside cells and watch dozens of different molecules at once -- by labeling them with short strands of light-up DNA that blink on and off with their own unique rhythm. Though they're all the same color, the technique makes it possible to distinguish as many as 56 types by their twinkling, more cheaply than traditional methods and without fading over time.

Tiny light-up barcodes help researchers identify DNA molecules

How do you identify one molecule among tens of thousands? Traditionally, scientists dye molecules in various colors. But what if each individual molecule had its own unique identifier? ...
