• Energy transmission by gold nanoparticles coupled to DNA structures
  

  Since the inception of the field in 2006, laboratories around the world have been exploring the use of ‘DNA origami’ for the assembly of complex nanostructures. The method is based on DNA strands with defined sequences that interact via localized base pairing. “With the aid of short strands with app more

• Water molecules are gold for nanocatalysis
  

  Nanocatalysts made of gold nanoparticles dispersed on metal oxides are very promising for the industrial, selective oxidation of compounds, including alcohols, into valuable chemicals. They show high catalytic activity, particularly in aqueous solution. A team of researchers from Ruhr-Universität Bo more

• Light at the end of the nanotunnel for future catalysts
  

  Using a new type of nanoreactor, researchers at Chalmers University of Technology, Sweden, have succeeded in mapping catalytic reactions on individual metallic nanoparticles. Their work could help improve chemical processes, and lead to better catalysts and more environmentally friendly chemical tec 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
