Scientists have developed the first liquid nanoscale laser. And it's tunable in real time, meaning you can quickly and simply produce different colors, a unique and useful feature. The laser technology could lead to practical applications, such as a new form of a 'lab on a chip' for medical diagnostics. In addition to changing color in real time, the liquid nanolaser has additional advantages: it is simple to make, inexpensive to produce and operates at room temperature.
