A Greener Way to Create Quantum Dots

Facebook X LinkedIn Email
BETHLEHEM, Pa., May 13, 2016 — A method for manufacturing quantum dots (QDs) from a single enzyme may provide a simple, cost-effective and environmentally friendly way to produce these semiconducting nanocrystals, prized for their optical and electronic properties. Current chemical manufacturing methods for QDs are time-consuming and often require toxic solvents. The discovery of a biological method to manufacture QDs using a single enzyme began when Lehigh University professors Bryan Berger, Chris Kiely and Steven McIntosh were asked to investigate a bacteria that was growing on metal surfaces at a nearby hospital....Read full article

    Glossary
    nanoparticle
    A small object that behaves as a whole unit or entity in terms of it's transport and it's properties, as opposed to an individual molecule which on it's own is not considered a nanoparticle.. Nanoparticles range between 100 and 2500 nanometers in diameter.
    electron
    A charged elementary particle of an atom; the term is most commonly used in reference to the negatively charged particle called a negatron. Its mass at rest is me = 9.109558 x 10-31 kg, its charge is 1.6021917 x 10-19 C, and its spin quantum number is 1/2. Its positive counterpart is called a positron, and possesses the same characteristics, except for the reversal of the charge.
    photon
    A quantum of electromagnetic energy of a single mode; i.e., a single wavelength, direction and polarization. As a unit of energy, each photon equals hn, h being Planck's constant and n, the frequency of the propagating electromagnetic wave. The momentum of the photon in the direction of propagation is hn/c, c being the speed of light.
