Observing nanoparticles and their diffusion near interfaces
Chemical and Biomolecular Engineering Building 1
Our inability to measure how nanoparticles move and rotate near interfaces is a stumbling block in understanding or controlling many colloidal systems (eg, the self-assembly of nanotubes, or the orientation of a drug-delivery particle near a substrate). This talk will outline two new laser microscopy techniques that enable us to observe label-free nanoparticles and their 3D diffusion near interfaces with nanometre resolution, at hundreds of frames per second, and without any sample preparation. The power to interrogate unadulterated nanoparticle systems with high spatiotemporal resolution will have broad implications across the material and life sciences.
