Researchers led by Josef Lazar of the Institute of Organic Chemistry and Biochemistry of the Czech Academy of Sciences (IOCB Prague) have demonstrated that molecules of fluorescent proteins act as ...

The research group proposed and tested a nano-antenna that uses the specific optical resonance of dielectric nanoparticles to form a near field of circularly polarized light. This technique bolsters ...

Optical antennas have already been shown to dramatically enhance molecular excitation and emission processes. Now, a compelling new study illustrates how they can redirect the emission of single ...

(Nanowerk News) In order to better understand fundamental processes in life science at the molecular level, the precise observation of single molecule dynamics is of utmost interest. However, current ...

(Nanowerk News) The proliferation of point-of-care testing, from at-home blood glucose meters to COVID-19 rapid tests, is accelerating and improving medical care. Continuing to upgrade the sensing ...

Researchers in Japan have built a nano-scale version of the classic antenna used to pick up TV signals in millions of homes around the world. The device, which is based on the “Yagi-Uda” antenna, ...

NIR fluorescence has shown great potential in bioscience, but low quantum-yield has largely impeded research on most NIR fluorophores. Here, scientists in China use asymmetric plasmonic nano-antennas ...
