• 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 in the bo 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.   more

• Xanthates and Trithiocarbonates Strongly Inhibit Carbonic Anhydrases and Show Antiglaucoma Effects in Vivo

  Dithiocarbamates (DTCs) were recently discovered as carbonic anhydrase (CA, EC 4.2.1.1) inhibitors. A series of xanthates and a trithiocarbonate, structurally related to the DTCs, were prepared by reaction of alcohols/thiols with carbon disulfide in the presence of bases. These compounds were tested more

• ATP-dependent regulation of actin monomer-filament equilibrium by cyclase-associated protein and ADF/cofilin

  Cyclase-associated protein (CAP) is a conserved regulator of actin filament dynamics. In the nematode Caenorhabditis elegans, CAS-1 is an isoform of CAP that is expressed in striated muscle and regulates sarcomeric actin assembly. Here, we report that CAS-2, a second CAP isoform in C. elegans, atten more

• Coherent Anti‐Stokes Emission from Gold Nanorods and Its Potential for Imaging Applications

  Abstract We used coherent anti‐Stokes scattering (CAS) to characterize individual gold nanorods (GNRs) and GNR aggregates. By creating samples with different densities of GNRs on silicon wafer substrates, we were able to determine surface coverage by scanning electron microscopy (SEM) and then c more
