Through these techniques with Cd-free QDs as stable fluorescent labels, researchers can observe the cell and tissue structure with higher resolutions and in a much more biocompatible way.
It is worth noting that these QDs are also flexible to conjugate with other agents such as metallic nanoparticles, radioactive labels and even Raman tags.
[11] Recently, Cd-free QDs have also shown great potential in the fabrication of new generation of solar cells and display applications.
[12][13][14] Quantum dots (QDs) have been a main focal point in the material science industry in the recent years, allowing scientists and engineers to manipulate and test the properties of these nanoscale particles to develop a better understanding of them.
Michael Sailor and his team including National Science Foundation (NSF)- supported researched at University of California, San Diego (UCSD), have developed the first nanoscale Cd-free QD that is able to glow brightly enough to allow physicians to examine internal organs.
