Identification of inorganic crystal-specific sequences using phage display combinatorial library of short peptides: A feasibility study

The feasibility of using a combinatorial phage display library of decapeptides to identify ligands which can interact with the surface of a crystal was assessed using geological calcium carbonate as a model. Two relatively strong binding clones were identified by ELISA, sequenced and the encoded oligopeptides were prepared by solid phase synthesis and their properties compared with those of casein hydrolysate.
