Researchers at the University of Texas at San Antonio and Northeastern University, both in the US, say they have succeed in synthesizing pure selenium quantum dots and nanoparticles by simply blasting a sample of selenium powder in a glass of water with a laser beam. The nanostructures might be used in two very different applications: as antibacterial agents and as photon harvesters in solar cells…..
