The journal Reaction Chemistry & Engineering published a paper Mar. 25, 2019 detailing a new process for synthesizing gold nanoparticles. The process reduces the time required to produce gold nanoparticles to under 4 minutes, and can produce particles with or without capping using carbon monoxide as gaseous reductant.
The paper, “Rapid Synthesis of Gold Nanoparticles with Carbon Monoxide in a Microfluidic Segmented Flow System,” by H Huang, et al, tested a variety of capping agents, including tri-sodium citrate, polysorbate 80, oleylamine and thiolated polyethylene glycols. According to the researchers, the parameters tested demonstrated that this process is flexible for a variety of applications.
After synthesizing their particles, researchers measured particle sizes of 3-25 nm using the CPS Disc Centrifuge.
Around the world, researchers rely on CPS Instruments when accuracy matters most. The CPS disc centrifuge provides a higher resolution than light scattering or particle counting methods at a much faster rate of analysis than competitive sedimentation-based particle sizing instruments. Whether replacing an aging system or increasing capacity with a new system, an investment in a CPS disc centrifuge is an investment in consumer confidence.
