he size dependent properties of noble metal nanoparticles
(MNPs) have created a great promise for their use in a
variety of optical, electronic and biomedical applications.
Nowadays, a great diversity of techniques such as chemical,
thermal, photochemical or biological and methods have been
developed for their synthesis. Among them, photochemical
approach has proven to be an excellent tool to synthesize
nanoparticles and also nanocomposite materials in the
investigation of the mechanistic aspects of their formation.
In particular, we present the advantages of a “green” and
“highly flexible” character and a strong control in both spatial
and temporal directions. In this context, firstly, we will use
photochemistry to generate MNPs through photo reduction
of a metal precursor using free radicals generated from
photosensitizers in an aqueous solution or directly generated
onto glass surfaces in order to produce plasmonic surfaces.
Thus, efficient nanoparticle synthesis and their morphological
control require a careful selection of experimental conditions
such as photonic and chemical parameters. Moreover, the
photochemical tool was used not only for the nanoparticles
synthesis, but also to obtain advanced nanomaterials as
nanocomposites metal/polymer. The hybrid nanocomposites
have been obtained by combing the
in situ
photoreduction
of MNPs with the acrylates monomers photopolymerization.
Specific interactions between the macromolecular network
and the nascent particles were funded to play an important
role insofar as they control the access of metal atoms to the
different crystalline planes of the growing nanoparticles, which
is necessary to obtain anisotropic objects. The assembling
process of MNPs in the polymer matrix was the next step
of our work. Controlling both the synthesis and multi-scale
organization (nano, micro and macro) of such cross-linked
organic-inorganic nanomaterials opens promising prospects
in the field of advanced materials.
Biography
Lavinia BALAN obtained the PhD degree from the University Henry Poincaré
in Nancy, France, in 2005. Her PhD was devoted to the elaboration of an
original material for the anode of Li-ion batteries. After a post doctorate in
Orleans and then in Mulhouse, she joined the Department of Photochemis-
try of Mulhouse in 2006 as a CNRS Senior Researcher. She opened a new
field of research in this laboratory, viz. the photo-assisted synthesis of metal
nanoparticles and metal-polymer Nano composite. Since December 2009,
L. Balan joined the Institute of Materials Science of Mulhouse (IS2M)-CNRS.
She has published more than 100 scientific publications, 4 book chapters
and 5 patents. Dr. L. Balan has been serving as an editorial board mem-
ber for few scientific journals. Lavinia BALAN research are concerned with
photochemical synthesis of metal/polymer nanocomposites and design,
customization and characterization of metal nanoparticles and nanocrys-
tals (quantum dots) suited for advanced applications in the fields of optic,
photonics, plasmonics, imaging or biology.
