Making and Characterising Silver Nanoparticles

Here’s a video demonstration of how to make silver nanoparticles, and change their colour easily by adding silver ion to a seed solution. Colour is monitored by UV/visible spectroscopy and some particle sizing is done by dynamic light scattering and TEM (transmission electron microscopy). This is a short overview video of a much larger interactive resource that will be published soon as part of the RSC HE STEM project. It’s also related to the Nanotechnology Workshop we developed for schools [PDF].


One thought on “Making and Characterising Silver Nanoparticles

  1. Hi, I am currently trying to write an IB extended essay on silver nanoparticles and whether the size of them affects their anti-microbial properties. I was wondering if you might be able to share any more knowledge such as chemicals involved and their concentrations as I am having trouble finding an in-depth method to create them. Thanks
