Accurate alignment of quantum dots with photonic components is critical for extracting the radiation emitted by the dots. In this illustration, a quantum dot centered in the optical "hotspot" of a ...

A rapid method for detecting and identifying very small numbers of diverse bacteria, from anthrax to E. coli, has been developed by scientists from the National Cancer Institute and the National ...

For the first time in history, the production of semiconductor quantum dots has been achieved at room temperature using lab-designed proteins, Princeton chemists reported in a paper published in the ...

Depending on their applications, quantum dots need to be tailored in terms of their structure and properties. Chemists have shown that quantum dots obtained by their novel method can be successfully ...

This method recovered 85% of the original quantum dots, which still performed almost as well as new ones. The recycled dots were then used to make lasers that worked just like the originals. The team ...

In what may be one of the first medical uses of nanotechnology, a chemist and a doctor who specializes in infectious childhood diseases have joined forces to create an early detection method for a ...

Synthesis of semiconductor quantum dots, characterization and their various applications are the frontier research areas at present [1-12]. Different techniques like MBE (Molecular beam epitaxy), RF ...
