Quantum Dots to Generate Higher Sensitivity Sensors for Cancer Applications
07/25/2016 01:00 PM EDT
Researchers at Emory University are developing the next generation of quantum dots for use as highly sensitive fluorescent sensors to detect cancer. This image is a transmission electron micrograph of quantum dot nanocrystals composed of a cadmium mercury telluride alloy core with several layers of zinc sulfide acting as a shell. These quantums dots are unique because the optical and electronic properties can be finely tuned by altering the composition of the ternary alloy core, a much more facile process than previous generations, without changing the particle size.
