Free position for a PhD position starting November 2016
Topic: DESIGN OF MONOLAYER PROTECTED GOLD NANOPARTICLES
FOR CONTROLLED SELF-ASSEMBLY
Supervision: Lucia Pasquato
and Paolo Pengo, Department of Chemical and Pharmaceutical Sciences, University
of Trieste, e-mail: lpasquato@units.it,
ppengo@units.it
Directed
self-assembly of nanometer-sized materials into ordered arrays are the most
widely studied targets of current research. The bottom-up approach for the
fabrication of functional materials is very attractive since it utilizes small and rather simple building
blocks that will self-assemble into larger, more complex nanostructures. For
these approaches, (bio)chemists are inspired by Mother Nature, who uses a large
variety of covalent and non-covalent interaction mechanisms. In this context we
are interested in developing new protocols to self-assemble anisotropic hybrid
organic-inorganic nanoparticles with a control over the assembly process to
give rise to well defined architectures. The project foresees the design and
synthesis of anisotropic gold nanoparticles, their modification with selected
functional groups and/or functional building blocks and the study of their
self-assembling process driven by different conditions. A variety of techniques
will be used to characterize the final material and to investigate their
optical and electronic properties.
