*Nano and microscale design of biosurfaces*

The main biotechnological applications (biosensors, biochips) require 
today the use of surfaces with specific properties at the 
micro/nano-scale. The development of low cost methods (without clean 
room facility) allowing modification and structuring of bio-surfaces is 
now a major technological challenge.

Our laboratory has been developing for several years, new methodologies 
for developing, structuring and characterization of surfaces with 
specific properties. We have recently demonstrated with our colleagues 
from INRA (French agronomy research center) the feasibility of 
micro-structuring biopolymers using specific enzymes. These results 
obtained recently are very promising in terms of applications, 
particularly in the areas of food, environment and design of fully 
organic nano-micro electric circuits.

In partnership with the INRA, the PhD student will begin by designing 
bio-functionalized surfaces using biopolymers from renewable resources. 
Surface structures will be performed on micrometer scale by soft 
lithography (also known as microcontact printing). By choosing the 
proper enzyme/biopolymer couple, positive or negative lithography can be 
performed. We'll then study different ways of depositing conducting 
polymers in the "open structure" to form micro/nano circuits whose 
conduction properties will be studied by AFM in electric mode. To carry 
out this project, the PhD student will be firstly introduced to methods 
of preparation of the structured biosurfaces and other techniques for 
structural (AFM), optical (micro-Raman confocal spectroscopy, 
fluorescence microscopy) and electrical characterizations (AFM). 
Finally, nanoscale design will be considered by using 
enzyme-functionalized AFM tip.
