Quantum dots are crystals of a fluorescent semiconductor material with a diameter of as few as 10 to 100 atoms (2-10 nm). They are used as labels for imaging molecules because of their very narrow ...

The chemical structure of a coal-derived graphene quantum dot. The dots were first synthesized at Rice University for medical imaging, sensing, electronic and photovoltaic applications ...

Bioluminescence is widely used for in vivo imaging of nude mice. By conjugating luciferase protein to quantum dots, bioluminescence resonance energy transfer (BRET) turns these useful fluorophores ...

Researchers demonstrate orbital hybridization in graphene-based quantum dots, revealing how anisotropic confinement ...

JILA scientists have found a way to suppress the blinking problem in quantum dots by bathing them in a chemical solution. This animated image, which demonstrates the basic blinking phenomenon ...

However, newly published research from the University of Oklahoma proves that adding a covering to one of these light sources, called a colloidal quantum dot, can cause them to shine without ...

Quantum dots are nanoscale man-made crystals that have the ability to convert a spectrum of light into different colors. Each dot emits a different color depending on its size. (Image: RNGS ...
