208th iCeMS Seminar: Drs Peter Jönsson and Hiroshi Uji-i

Dr Peter Jönsson

Intermolecular interactions between molecules on the surface of immune cells
Dr Jönsson will in this seminar review some of his recent work on studying intermolecular interactions between molecules on the surface of immune cells. This includes both 2D affinity measurements between proteins in cell-cell contacts, as well as measurements of the lateral chemical potential of these molecules, obtained using a technique called hydrodynamic trapping.

Prof Hiroshi Uji-i

Plasmonic remote-excitation of Raman spectroscopy for single cell interrogation
In this talk, a noble Raman/fluorescence nanoscopic techniques using sub-diffraction limit SPPs waveguiding will be introduced. Specifically, we demonstrate that SPPs launched along a silver nanowire (50 ~ 100 nm diameter) can remotely excite SERS and SEF in the vicinity of the nanowire surface due to the SPPs wave-guiding effect. The ability to transfer SERS/SEF excitation over several microns, through sub-diffraction limited structures, will be discussed with respect to potential application toward super-resolution endoscopy and tip-enhanced Raman microscopy.
