News Gold Nanoparticles

• Applying precious metal catalysts economically
  

  Precious metal nanoparticles of platinum and gold are excellent catalysts. But they are expensive and rare. This new method makes it possible to save material. Researchers at Ruhr-Universität Bochum and the Fritz Haber Institute Berlin have developed a new method of using rare and expensive catalyst more

• Nanotechnology and sunlight clear the way for better visibility
  

  A new coating developed by ETH researchers prevents fogging on transparent surfaces. Rather than using electricity, the coating relies on sunlight to heat the surface. Anyone who skis, wears glasses, uses a camera or drives a car is familiar with the problem: if you come into a humid environment fro more

• Carrying and releasing nanoscale cargo with 'nanowrappers'
  

  This holiday season, scientists at the Center for Functional Nanomaterials (CFN)--a U.S. Department of Energy Office of Science User Facility at Brookhaven National Laboratory--have wrapped a box of a different kind. Using a one-step chemical synthesis method, they engineered hollow metallic nanosiz more

• Dual mode detection of amifostine based on gold nanoparticles and sulfanilic acid functionalized graphene quantum dots

  In this work, we developed a versatile dual-readout (colorimetric and fluorometric) amifostine (WR2721) sensor based on the inner filter effect (IFE) of gold nanoparticles (AuNPs) on sulfanilic acid functionalized graphene quantum dots (SGQDs). The fluorescence of SGQDs can be adequately suppressed more

• Microwave-Assisted One-pot Synthesis of Anisotropic Gold Nanoparticles with Active High-Energy Facets for Enhanced Catalytic and Metal Enhanced Fluorescence Activities

  A simple sustainable method has been reported for the synthesis of highly active Au nanoparticles (NPs) having sharp edges and corners using oxalic acid as a reducing agent. Different chloroauric acid to oxalic acid mixing ratios were studied and found that 1:3 ratio gives better structures with hig more

• A highly sensitive glucose sensor based on a gold nanoparticles/polyaniline/multi-walled carbon nanotubes composite modified glassy carbon electrode

  An amperometric glucose sensor, PTFE/GOx/AuNPs/PANI/MWCNTs/GCE, was assembled layer-by-layer using multi-wall carbon nanotubes (MWCNTs), polyaniline (PANI), and gold nanoparticles (AuNPs) for electrode surface modification and a fixed glucose oxidase enzyme (GOx) carrier. Methods such as cyclic volt more
