DESCRIPTION:Structure and Dynamics of Supramolecular Systems one\nMolecule 
 at a Time\nBy Gonzalo Cosa (Chemistry\, 91Ë¿¹ÏÊÓƵ)\nAdvances in electronics\,
  optics and nanotechnology have led to a\ntremendous progress in optical i
 maging over the past years. In the\nspecific case of fluorescence imaging\
 , the possibility of\nvisualizing single fluorescent molecules with exquis
 ite\nspatial and temporal resolution gave rise to the field of Single\nMol
 ecule Spectroscopy (SMS). This technique has provided new\nparadigms in ch
 emical biology\, biochemistry and biophysics by\nrevealing unique informat
 ion otherwise hidden in ensemble\nmeasurements.\nA major interest in our r
 esearch activities is to expand SMS\nmethods to study and characterize nan
 omaterials and supramolecular\nsystems. In this presentation I will descri
 be our recent progress\non the single particle imaging of DNA nanotubes of
  various\narchitectures. I will also discuss our single molecule spectrosc
 opy\ncharacterization of liposome beacons\, liposomes encapsulating water
 \nsoluble conjugated polyelectrolytes\, with an emphasis on their role\nin
  biosensing platforms. In closing\, I will also address our single\nmolecu
 le mechanistic enzymatic studies\, where we are investigating\nthe molecul
 ar structure and dynamics of key protein/nucleic acid\ncomplexes that are 
 intermediates in polymerase catalyzed RNA\nsynthesis.\n \n
