Aug 28, 2020 (Nanowerk News) Plasmonic surface lattice resonances (SLRs) supported by metal nanoparticle arrays have many merits such as strong field enhancements extended over large volumes, as well as long lifetimes, narrow linewidths, angle-dependent dispersion, and a wide range of wavelength tunability. In order to improve the performance of...

But the image on the right has been super resolved using Dr. Yu Ding's new image processing method. CREDIT ...

Aug 13, 2020 (Nanowerk News) North Carolina State University researchers have demonstrated a new technique for creating ultrasound images. The new approach is substantially simpler than existing techniques and could significantly drive down technology costs. “Conventional ultrasound devices have a receiver that detects ultrasonic waves and converts them into an...

Aug 13, 2020 (Nanowerk News) A Princeton team has developed a class of light-switchable, highly adaptable molecular tools with new capabilities to control cellular activities. The antibody-like proteins, called OptoBinders, allow researchers to rapidly control processes inside and outside of cells by directing their localization, with potential applications including protein...
