A newly invented mesoporous silica (silica) nanoparticle is said to have the highest brightness in the world and is the brightest nanoparticle in the world--quantum dots (quantum dots)-- Bright 34 times.
According to the Clarkson University of the United States (Carkson University), this transparent silica hull hides light-emitting nanoparticles inside rather than using quantum confinement like quantum dots (quantum- Confinement) works with higher brightness.
Igor Sokolov, a professor of physics at Clarkson University, said that this bright mesoporous silica nanoparticle has the potential to be used in medical, biological, material science and environmental protection applications to enable more accurate detection of contaminants in the environment and Biosensors, defense detection devices, etc.
The principle of light-emitting nanoparticles is to absorb light of a single wavelength and then emit it in other places; through functionalization, such particles can emit light only when the target to be measured appears. The use of ultra-sensitive nano-particles allows trace amounts of contaminants or poisons to be detected.
The method used by Sokolov is to seal a large amount of organic light-emitting molecules inside the mesoporous silica hull (20-50 nanometers in diameter); to illustrate the brightness, he expressed the brightness of those particles with a diameter of about 40 nanometers. Higher than the diameter of 25-30 nanometers of water-dispersed quantum dots - is currently known as the highest brightness quantum dots.

The above studies were conducted by Sokolov together with postdoctoral fellows Shajesh Palantavida, Eun-Bum Cho (currently Assistant Professor of Science and Technology, Seoul National University), and a Ph.D. student Dmytro Volkov, and were developed by the National Science Foundation (NSF) and the U.S. Army.
