SUMMARY:Conférence 3/3 de la Professeure Nelsi Zaccheroni (Bologna)
DESCRIPTION:Titre : From Molecular to Nanostructured Luminescent Chemosenso
 rs.Endroit : Pavillon J.-A.-Bombardier\, salle 1035 de 10 h à 11 h.Hôte 
 : Professeur William Skene.
\nLa conférence sera prononcée (en anglais) 
 par la professeure Nelsi Zaccheroni\, du Département de chimie de l'Unive
 rsity of Bologna (Italie).
\nRésumé : Chemical analysis has been improve
 d by the advent of sensory devices based on chemosensors that are able to 
 transform chemical information (composition\, concentration\, etc.) into a
 n analytically useful signal. These devices\, in fact\, find applications 
 in many different areas of great social and economic impact. Among all the
  possible alternatives of chemosensors\, we focussed our research activity
  on luminescent chemosensors as they present many advantages: sensitivenes
 s\, low cost\, ease of use\, versatility\, and they offer the possibility 
 to reach sub-nanometer spatial and sub-millisecond temporal resolution. Ou
 r design of efficient chemical sensors is mainly based on the principles o
 f supramolecular chemistry: the assembly of different moieties with each o
 ne devoted to a precise function. In this seminar\, some systems involving
  supramolecular species for the detection of metal ions relevant to the bi
 omedical and environmental fields will be examined. The application of the
 se nanostructures brought us to explore the possibility of moving from mon
 ofluorophoric systems to multifluorophoric ones\, to try and obtain signal
  amplification effects thanks to local organization. Moreover\, core-shell
  nanoparticles can also make organic chemosensors suitable for environment
 al and biological applications in water.
