IPPG Connection presents
MEETUP ABOUT MICROFLUIDIC & MORE
Every Third Wednesday of each month, 11 AM - noon.
6, rue Jean Calvin
75 005 PARIS.
As before, this meeting will be focused on the physics underlying biological interactions at microscale. Microscale technologies are emerging as powerful tools for tissue engineering and biological studies. The use of microfluidics, surface patterning, and patterned co-cultures in regulating various aspects of molecular and cellular microenvironment has been increasingly sought to. In “Microscale Affairs”, we aim to discuss these tools, related techniques and their applications.
11.00 AM - NOON

Design of porous composites by assembling MOFs with (bio)macromolecules or carbon based materials
Hybrid nanocomposites offer unique advantage to enable integration, miniaturisation and multi-functionalisation of devices. In the past few years, significant research interest was devoted to Metal–Organic Frameworks (MOFs) due to the precise and remarkable design of their framework and porosity at the molecular length scale. MOFs are thus considered as an intriguing class of porous materials with a high potential for numerous applications including gas storage/separation, catalysis, sensing, electronics, biomedicine etc... The assembling of MOFs with a variety of organic components and functional nanoparticles was envisaged not only to process MOFs and enhance their stability but also to impart synergistic functionalities. Here we present our progress in the development of MOFs based composites to address environmental and energy-related applications. First, we have explored different strategies to process MOF-polymer mixed matrix membranes for CO2 capture and proton conductivity.
Since the transport properties of the membranes result from a strong interplay between their morphology, thickness, microstructure and the balance between hydrophilic/hydrophobic regions, we have optimized the morphology/diameter and surface functionalization of MOFs nanoparticles for their integration in the polymer matrix. We have also taken profit of the self-organization properties of (bio)polymers or graphene oxide to tune the organization and nanostructuration of composites as well as construct novel hybrid architectures through interfacial synthesis. Our ultimate objective was to expand this approach towards enzymes for the design of novel biocatalysts or modified electrodes. We have combined advanced characterization tools (TEM analytical and imaging techniques and SAXS) to provide acomplete picture of these composites at the nanoscale and describe their interfacial properties
