Optical labeling is an important tool in biological imaging because it offers superb discrimination between the sites of interest and the crowded background of a biological specimen. Diamonds nanocrystals have several advantages over other optical labels and open new opportunities in optical imaging, especially in applications where the size of optical labels represents an important parameter.
Researchers in Germany managed to integrate quantum dots (QD) into the walls of nano- and microtubes. This novel structure serves as a quantum light emitter as well as optical waveguide. This represents a major step toward the realization of flexible high quality factor optical resonators based on tubes.
Nano Zinc Oxide (ZnO) and Carbon Nanotubes (CNTs) are arguably two of the most studied nanomaterials in recent years. Combining these two nanomaterials into hybrid nanomaterial presents a fascinating nanosystem for further investigations.
Researchers in the UK and Germany told Nanowerk that they developed a simple, fast and efficient method for fabricating metallic photonic crystals. This new method opens the door to a number of applications in telecommunication, all-optical switching, sensors, and semiconductor devices.
The application of phase and polarization control may lead to guidance of light in the nanoscale via metal nanoparticle arrays.
Researchers at the Korea Institute of Science and Technology (KIST) succeeded in fabricating a fascinating ZnO nanosheet structure.
A novel micro-reactor approach for fabricating self-organzed, photosensitive gold-peapodded silica nanowires has been developed by a group of researchers in Taiwan.
Properties of recently discovered photonic nanojets make them an ideal tool for detecting, differentiating and sorting nanoparticles, researchers at Northwestern University told Nanowerk.
