We report that rhomb-shaped metal nanoantenna arrays support multiple plasmonic
resonances, making them favorable bio-sensing substrates. Besides the two localized …

Spontaneous emission of fluorescent molecules or quantum dots is radiated along all
directions when emitters are diluted in a liquid solution, which severely limits the amount of …

Plasmonic antennas offer extremely promising strategies to enhance single molecule
fluorescence sensing and breach the limitations set by diffraction. However, the technical …

Polarizers provide convenience in generating polarized light, meanwhile their adoption
raises problems of extra weight, cost, and energy loss. Aiming to realize polarizer-free …
