Interferometric Single-Molecule Microscopy

Authors: George Rajna

In a study published online in Nature Methods, Prof. Xu Tao and Prof. Ji Wei from the Institute of Biophysics of the Chinese Academy of Sciences developed a new interferometric single-molecule localization microscopy process with fast modulated structured illumination, called Repetitive Optical Selective Exposure (ROSE). [33] However, a discovery published in the journal Science by Professor Nikolay Zheludev and Dr. Guanghui Yuan at NTU's School of Physical & Mathematical Sciences describes a new optical method that can measure displacements of a nanometer—the smallest distance ever directly measured, using near infrared light. [32] Compact quantum devices could be incorporated into laptops and mobile phones, thanks in part to small devices called quantum optical micro-combs. [31] Taking their name from an intricate Japanese basket pattern, kagome magnets are thought to have electronic properties that could be valuable for future quantum devices and applications. [30] A team of Cambridge researchers have found a way to control the sea of nuclei in semiconductor quantum dots so they can operate as a quantum memory device. [29] Researchers successfully integrated the systems-donor atoms and quantum dots. [28] A team of researchers including U of A engineering and physics faculty has developed a new method of detecting single photons, or light particles, using quantum dots. [27] Recent research from Kumamoto University in Japan has revealed that polyoxometalates (POMs), typically used for catalysis, electrochemistry, and photochemistry, may also be used in a technique for analyzing quantum dot (QD) photoluminescence (PL) emission mechanisms. [26] Researchers have designed a new type of laser called a quantum dot ring laser that emits red, orange, and green light. [25] The world of nanosensors may be physically small, but the demand is large and growing,
