Scientific domain : This thesis will explore novel concepts of 'smart' microarrays based on merging the plasmonic and polymer fields. The
scientific domains which are involved concern nanooptics (optical properties of gold nanostructures, opto-thermal conversion induced by
surface plasmon) and surface chemistry (functionalization of gold nanoparticles by polymer brushes, thermoresponsive polymers, wettability
properties). The supervising group has the complementary expertise in these domains.

Description of the research work proposed for a PhD
Title : Hybrid thermoresponsive polymer/plasmonic nanostructures for opto-thermally induced switchable surface wettability
Patterned biomolecular arrays with nanoscale features are useful for applications such as tissue engineering, cell cultures, and studying subcellular
receptor-ligand interactions and intracellular processes. A promising tissue engineering approach relies on the use of surfaces grafted with
thermoresponsive polymers such as poly(N-isopropylacrylamide) (PNIPAM). The basic idea is that this polymer exhibits a temperature-dependent solution
and surface behavior allowing the control of adhesion/detachment of protein or cell on PNIPAM-modified substrates via a temperature switch.
In this project, we propose to combine thermoresponsive polymers with light-activated plasmonic heaters (gold nanoparticles) in order to design a new
generation of switchable bioadhesive platforms for “smart” lab-on-a-chip device. The candidate will be involved in the development of chemical strategies
for the surface functionalization of gold nanodot arrays by thermoresponsive polymer brushes and the study of (bio)adhesion on the resulting ‘smart’

Expected collaborations in Vietnam
This tesis will be developed in collaboration with Mrs. Tran Hong Nhung from the Laboratory Laser Spectroscopy, Centre of Quantum Electronics
Institute of Physics, Vietnam Academy of Science and Technology (VAST). She is now in charge of “Photonics Materials” and “NanoBiophotonics”, and
is interested in the use of optical nanoparticles for biolabeling and applications of nanostructures in Biology and Medicine. Applications in biology, using
the hybrid plamsonic strucutures, are expected thanks to this collaboration (Email : email@example.com or firstname.lastname@example.org).
