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:
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.
Specific peptides offer different benefits as detection tool:
