This invention relates to polypetides which bind to EGFR family receptors and to applications of those polypetides in medicine, veterinary medicine, diagnosis diagnostics and imaging. The polypetides comprise an EGFR binding motif consisting of an amino acid sequence selected from i) EX2X3X4AX6X7EIR X11LPNLNGWQX20 TAFIX25SLX28D and ii) an amino acid sequence having at least 85% identity to the sequence defined in i).
