A scientific breakthrough was recently done by a group of scientists developing a nanoscale laser in liquid form for the first time as reported by Science World Report news.
The laser is able to tune real time meaning good news for users as they can simply and quickly produce various colors that could even lead to useful and important medical applications.

According to lead researcher Teri Odom, the liquid nanolaser is simple and easy to make, can operate at normal room temperature and most importantly, does not cost too much to produce. With this development, it can lead to new forms of laboratory on a microchip for medical wonders.
To clarify, the liquid nanolaser is not simply a laser pointer but a laser device placed on a chip. The color produced by the laser can be refined when the microfluidic channel's dye located above the cavity of the laser is changed.
The cavity of the laser is composed of an array of gold and reflective nanoparticles wherein the concentrated light around it is amplified. With this laser, it does not require mirrors to have the light bounce from it to create a laser. As the color of the laser is aptly tuned then the nanoparticle is fixed and never changes.
Odom said that their study has allowed them to think of the new laser designs and what else can it make. She also stated that her laboratory and her staff like to consider new structures, materials and strategies to put them together to come up with unimagined things yet to come.
She also believes that with the work they have, it will conceptualize an advanced engineering for reversible and on-demand controlled light from various nanoscopic sources.
