Lecturer:

Guido Panzarasa, M.Sc., Department of Science and Technological Innovation, University of Eastern Piedmont "Amedeo Avogadro", Alessandria (Italy)

Guido Panzarasa was born in 1988. He obtained a B.Sc. in Materials Science in 2010  and a M.Sc. in Chemical Sciences in 2012 from the University of Eastern Piedmont "Amedeo Avogadro", Alessandira (Italy) working on the synthesis and characterization of core-shell silica nanoparticles for plasmonic and photonic applications. He started his PhD in 2012 in the same Insitution under the supervision of Dr. Katia Sparnacci, focusing on the realization of patterned, functional polymer brushes by means of controlled radical polymerization.

 

Titel:

Silicon Dioxide: a Playgrund for Nanotechnology and Surface Engineering

Abstract:

Since the seminal work of Stöber et al. [1] silica nanoparticles and functional siloxanes have become fundamental building blocks for the realization of complex structures on the nanoscale and for surface engineering by self-assembled monolayers (SAMs). Controlled synthesis of silica nanoparticles by sol-gel techniques, along with the major factors affecting diameter and monodispersity, the chemistries enabling introduction of functional groups and subsequent loading with pro-drugs, flourescent probes and noble metal nanoparticles for applications in drug delivery, photonics and plasmonics will be discussed thoroughly. The relevance of SAMs for smart coatings will be also highlighted by taking advantage of real case studies.
