T

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.
