In the field of applying phage display technology and Magic™ sequencing technology, Creative Biolabs has accumulated extensive experiences to select good binders with high specificity and affinity from our diverse phage display libraries on our advanced phage display platform. We are pleased to share our cutting-edge technology in providing the service of inorganic molecule binding peptides identification to our customers.

The Background of Inorganic Molecules as Substrates of Phage Display

Phage display is a powerful tool for the selection of short peptide ligands with high affinity. It has been utilized for more than two decades for the identification of short peptides, which bind to the substrate of interest with high selectivity. While primarily used for the identification of ligands to proteins, the scope of targets for phage display has significantly expanded. Based on the affinity selection of phage peptides libraries, more and more peptides binders that specifically bind to substrates, including natural or synthetic polymers, organic molecules, have been identified. Nowadays, phage display has also been applied to identify ligands with high affinity to a broad range of other substrates. With its rapidly expanding scope, there is more and more evidence shows that the phage display technique allows the identification of specific peptide binders to a myriad of inorganic molecules, including metal, metal borides, metal oxides, metal sulfide, magnetic materials, semiconductor, etc. These binding peptides can serve as templates to control the nucleation and growth of inorganic nanoparticles. Moreover, the integration of two different binding motifs into a single phage, which makes a bifunctional phage, could be useful for the generation of new composite materials.
