DESCRIPTION:Titre : Merging Nanotechnology and Luminescence Signalling: Dye
 -Doped Silica Nanoparticles for Biomedical Applications.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 Ne
 lsi Zaccheroni\, du Département de chimie de l'University of Bologna (Ita
 lie).
\nRésumé : Among the numerous possibilities of functional nanostru
 ctures\, we focused on new dye-doped silica nanoparticles and we investiga
 ted different synthetic approaches to obtain mono-disperse\, water soluble
  nanoparticles (NPs) with a silica core (10 nm diameter) and an organic sh
 ell (7 nm thick) that can host a certain number of dyes of different natur
 e. The optimization and proper design of these materials allowed us to mov
 e from the study of molecular luminescent labels to nanostructured species
  presenting improved properties. The fluorophores can be irreversibly incl
 uded into the nanoparticles to obtain very bright and photostable nanoobje
 cts with tunable emission spectral profiles and excitation wavelengths. Mo
 reover\, their chemical versatility allows them to be coupled with suitabl
 e biomolecules for specific target recognition. Incorporation of dyes acti
 ve in the therapeutic and diagnostic transparency window facilitates the e
 xcitation and detection of the NPs through biological tissues and\, theref
 ore\, their implementation for medical applications. Examples of in-vivo\,
  ex-vivo and in-vitro imaging will be presented.
