Researchers use nanoparticles to increase light frequency and resolution of imaging systems
Physicists at the Australian National University (ANU) are using nanoparticles to develop new sources of light that will allow us to "peel back the curtain" into the world of extremely small objects—thousands of times smaller than a human hair—wi.....»»
NASA retires mineral mapping instrument on Mars Reconnaissance Orbiter
NASA switched off one of its oldest instruments studying Mars on April 3, a step that's been planned since last year. Riding aboard NASA's Mars Reconnaissance Orbiter, CRISM, or the Compact Reconnaissance Imaging Spectrometer for Mars, revealed miner.....»»
New single-nucleotide polymorphism chip that can help identify genetic markers of desirable traits in rice
Genetic markers such as fragment length polymorphisms (RFLP), simple sequence repeats (SSRs), and single-nucleotide polymorphisms (SNPs) provide unique identifiers for individual organisms. This aids the identification of significant genetic variatio.....»»
Fluorescent aromatic nanobelts with unique size-dependent properties
A new type of aromatic nanobelt, methylene-bridged [n]cycloparaphenylene ([n]MCPP), has been synthesized and its properties elucidated by researchers at the Institute of Transformative Bio-molecules (WPI-ITbM) at Nagoya University in Japan, in collab.....»»
Highly sensitive Raman probe detects enzyme expression in heterogeneous tissues
Raman imaging offers a greater potential for detecting multiple enzyme activities than fluorescence imaging, demonstrate Tokyo Tech researchers by developing 9CN-rhodol-based activatable Raman probes using a novel mechanism for Raman signal activatio.....»»
Generation of color-tunable high-performance LG laser beams via Janus OPO
Laguerre-Gaussian (LG) modes are a type of light wave that can carry the external torque of photons as they move through space. They are useful in many fields, from optical communications to super-resolution imaging. Advanced developments in these an.....»»
