Dark-field microscopy coupled with capillary electrophoresis to see gold nanoparticles
Chinese scientists have combined interfacing dark field microscopy (DFM) with capillary electrophoresis (CE) and used it to “see” single gold nanoparticle (AuNPs) movement visually and in real time. The study also served to confirm the separation rules and fundamental theories of CE. more
Tooth enamel restoration inspired by mother of pearl
Researchers in China have shown that the organic component of mother of pearl can help repair damaged teeth, by acting as a template for the mineralisation of tooth enamel.
Tooth enamel is made up of rod-like crystals of hydroxyapatite, a calcium phosphate mineral. It is the hardest tissue ... more
Parallelogram shaped nanowires control light in two dimensions
A novel zinc oxide microwire optical resonator with parallelogram-shaped cross section has been made by chemists. The material can effectively control light in two dimensions, and could play the part of a building block in the development of optoelectronic devices.
