Specific peptides



Nature offers various materials showing great properties. Nacre is one of the best examples. In fact this is a composite of proteins and calcium carbonate. These proteins are able to promote and control the growth of the structure by binding specifically calcium carbonate particles to build a hierarchically assembled material showing high robustness and flexibility.

 Based on this concept, Symbiose Biomaterials has been working for a few years on specific peptides (or GEPI for Genetically Engineered Peptides for Inorganics) which are biologically selected to recognize and bind specifically an inorganic or organic substrate.

 Examples of targets:

  • metals (Au, Ag, Pt, Pb,…),
  • metal oxides (ZnO, Cu2O, TiO2, SiO2, Al2O3,…),
  • oxides and salts (Cr2O3, CaCO3, Fe2O3,…),
  • semi-conductors (GaAs, ZnS,…),
  • ceramics (hydroxyapatite, zeolites…),
  • polymers,
  • bacteria,
  • pesticides,
  • carbon nanotubes,

Applications (patent pending)

Such peptides allow the specific detection and possibly the sorting of chemical elements (on flat surfaces, powders, ores…) using a rapid, environmentally friendly and easy-to-industrialize process.
