Abstract: 

Development of the optical microscopy method 3D Multi-Resolution Microscopy combines the robust single particle tracking capability of 3D-Dynamic Photon Localization Tracking (3D-DyPLOT) with the optical sectioning power of Two-Photon Laser Scanning Microscopy (2P-LSM) and an electrically-tunable lens (ETL) to image the three-dimensional environment surrounding the locked-on particle. This resulting 3D image provides important biological context about the location and activity of the particle being tracked. This method will allow for the exploration of high-speed interactions between nanoparticles and larger structures at 3D interfaces.
