With the aim of studying biomolecules-surfaces interactions, the researchers develop various approaches for characterizing the surface chemistry of materials and determining which parameters are essential for controlling both protein adsorption and grafting. The most notable recent development has been a new protein grafting method using glycosylations.
Biomaterials Development – Characterization
K. Anselme, F. Bally-le Gall, J. Parmentier, T. Petithory, A. Ponche, V. Roucoules
With the prospect of improving existing biomaterials and developing new biomaterials, we link our skills in materials and biology to optimise their bioactivity. Much of the work concerns the functionalization of surfaces with biomolecules and the analysis of their effects on biological objects. The originality of our approach is the combination of advanced physico-chemical characterization techniques with biochemical and biological ones.

We are renowned for our work on the cellular response to topography at scales smaller than or equal to cell size. Original results have revealed a fascinating nuclear deformation phenomenon of cancer cells on micropillared substrates. This ability to deform cancer cells could be related to the deformation capacity of metastatic cells during their migration through biological tissues. More recently, we have discovered a phenomenon we call “Curvotaxis” which is the ability of cells to read the curvature of their environment.

Synthesis of materials from biological objects
A. Simon-Masseron, T. Petithory, K. Anselme
In recent years, researchers have been developing the synthesis of metallophosphate-based porous materials from biological objects. Thus, the use of amino-acids, nucleotides or phospho-proteins such as casein have made it possible to obtain original biosourced microporous zincophosphates. They have been doped or not with silver nanoparticles which give them biocidal properties without compromising their biocompatibility.

Process engineering for biological applications
K. Anselme, J. Brendlé, B. Lebeau, A. Ponche, O. Soppera
The interdisciplinary nature of the axis makes it possible to develop innovative processes for biological applications. We are currently investigating the influence of hydrodynamic parameters on the filtration of biomolecules. Another example is the development of an alternative method of cell sorting which aims to isolate target cells from a heterogeneous population (e.g. blood) using a specific and non-toxic approach based on photochemical cleavage.
