Peptides derived from phage display typically show significantly weaker binding than their respective high affinity phage, which can bind to protein surfaces in a multivalent fashion. Here we show that mimicking key aspects of the multivalent architecture of the phage on an AB(5) dendriticwedge can enhance the affinity of a phage-display derived collagen binding peptide 100-fold (K(d) = 550 nM), allowing
