Engineers Develop New Sensor to Detect Tiny Individual Nanoparticles

The image shows arrays of self-referenced and self-heterodyned Whispering-Gallery Raman microlasers for single nanoparticle detection. A "pump" laser generates a single Raman lasing mode inside the silica resonators. Upon landing of a nanoparticle on the resonator, Raman laser circulating inside the…

Engineers Develop New Sensor to Detect Tiny Individual Nanoparticles

Raman scattering process: A photon with shorter wavelength from a "pump" laser loses portion of its energy for being scattered by silica molecules and is converted to a 'signal' photon of longer wavelength (labelled as Raman signal) together with a "phonon."…

Faster, Cheaper Tests for Sickle Cell

This is a capillary tube showing a positive test for sickle cell disease. The system works by using polymers which self-assemble into layers which can separate red blood cells according to their density. The more dense cells infected with sickle cell…

A Nucleotide Change Could Initiate Fragile X Syndrome

Researchers used genetic mapping to determine that stem cells derived from mothers carrying a fragile X premutation (above) show a normal pattern of DNA replication when a nearby DNA sequence is similar to normal stem cells. Credit: Gerhardt et al., 2014
