DESCRIPTION:Stable and large-scale optical nanostructures can be inscribed 
 as surface relief in solid thin films of azobenzene materials. This occurs
  due to a unique photomechanical effect in which azobenzene molecules phys
 ically displace due to laser light\, enabling the creation of distinct mac
 ro-scale patterns that mimic a laser interference pattern. This nanofabric
 ation technique allows the creation of quasi-crystals and metasurfaces tha
 t\, when coated with a metal layer\, exhibit plasmonic properties in custo
 mizable narrow-band or wide-band wavelength regions. The resulting plasmon
 ic nanostructures have been used by our group as biosensors for detecting 
 proteins and bacteria\, below the clinical threshold for disease detection
 \, and they enabled the enhancement of Raman spectroscopy signals for the 
 detection of toxins and contaminants in liquids. Furthermore\, we develope
 d novel imaging techniques that selectively enhance\, filter and detect cu
 stomizable wavelength bands using polarization-contrast imaging enabled by
  two-dimensional gratings\n\nSpeaker(s): Prof. Ribal Georges Sabat \, \n\
