n TITLE
Metamaterial
Assisted Optical Nanoscopy
n ABSTRACT
Recent
discoveries in electromagnetic metamaterials have added new functionalities and
possibilities to the exciting research field of advanced optical microscopy,
and led to substantial improvements in imaging modality and resolution. In this
talk, I will present my recent studies using metamaterials to develop super-resolution
optical imaging techniques. The lateral resolution barrier was broken by a
structured illumination technique with large-spatial-wavevector illumination
patterns provided by the metamaterials, while the distance-dependent
photobleaching dynamics of fluorophores on the metamaterial substrate enabled
high-precision axial localization of each fluorophore; a three-dimensional
super-resolution imaging is possible by combining both the lateral and axial
dynamics. This metamaterials-assistant advanced imaging technique has
significant impact on cell biology and nanophotonics, enabling researchers to
unveil the subtle structure of cellular architectures and surface morphology of
nanostructures.
