Scientists from the Northwestern University have developed the first liquid nanoscale laser technology that can lead to the improvement of such practical application like “lab on a chip” that are meant for medical diagnostics.

The good thing about the nanoscale laser is that it can be reorganized in real time and it only means that varieties of colors can be produces easily by using the laser. Other feature of the nanolaser that makes it different from others is its simplicity, reasonable when it comes to cost and production as well as it can operate at room temperature.

It was in 2009, when demonstrations are presented as the laser are found only in research labs. Scientists do have confidence with the device as it greatly attracted them as it is an effective and useful technology that can even be used not just for medical purposes but also for military operations.

“My lab likes to go after new materials, new structures and new ways of putting them together to achieve things not yet imagined. We believe this work represents a conceptual and practical engineering advance for on-demand, reversible control of light from nanoscopic sources,” said lead research Teri W. Odom.

The journal Nature Communications published the findings of the study titled ‘Real-time Tunable Lasing from Plasmonic Nanocavity Arrays’. It was explained and clarified that the liquid nanolaser that they develop is not a laser pointer but rather a laser device on a chip.

The liquid dye in the microfluidic channel that is placed above laser’s cavity that help change the laser’s color in real time. Laser’s cavity does made use of reflective particle. Once tuning of the laser color is done, the nanoparticle cavity does stay in place.
