Abstract: 

I will discuss an interesting method we developed some time ago which we are now resurrecting in our  lab, hoping to brainstorm additional uses for it. 

The method can detect and track individual, unlabeled nano-particles as small as single viruses (~26 nanometer in diameter) over many times scales (from 10^-3 to 10^3 seconds) as they freely float in solution. The method enables measuring the mass of the nanoparticles (and changes of it), as well as their diffusion and hydrodynamic properties. Moreover, the method enables measurements of interactions between nanoparticles at high rates.

The original purpose this method was developed for was to measure the self-assembly process of single viruses. While the method managed to track and measure intact viruses at unprecedented rates, it failed to track the self assembly process because chemistry. Nevertheless, I believe, and will try to convince you, that this method offers a unique tool for the study of nanoparticles and their interactions, and I hope to generate a lively discussion in search of new applications for it.
