Clean launching of nanoparticles

In our recent work published in AIP Advances (arXiv) we show that we can shake off glass nanoparticles as small as 43 nm in radius (we didn't have smaller particles available!) from PTFE (Teflon) coated microscope slides. Typical launching velocities are well below 1 m/s, thus potentially allowing for readily available capturing methods. Our launching technique will be of use for the next generation of experiments as it's clean, thus enabling operation in ultra-high vacuum conditions.
