Bio-inspired chemistry and structures

Bio-inspired chemistry is an attractive approach to design organic (nano)materials with tailored properties for novel types of coatings, biosensors, delivery systems, etc.

In this frame, the Laboratory for Chemistry of Novel Materials has developed approaches of supramolecular design, theoretical modeling, (chir)optical spectroscopy, and advanced scanning probe microscopy on a series of bio-inspired and biologically-relevant structures, such as :

  • Nucleic Acids as templates for tailoring the assembly/polymerization of functional molecules
  • DNA hybridization biosensors based on ?-conjugated polyelectrolytes
  • Polymer coatings for stimuli-responsive bioadhesives
  • Fiber-forming biomolecular structures : cellulose nanowhiskers, peptide hydrogels
