Patent ID: 7598344

Claim:
An engineered bifunctional peptide comprising: a first peptide binding domain with length of about 7 amino acids to about 30 amino acids which binds selectively to a biomaterial wherein the first peptide binding domain is defined as a peptide amino acid sequence selected from the group consisting of the amino acid sequence of SEQ. ID. NOS.: 1-22; a second peptide binding domain with length of about 7 amino acids to about 30 amino acids which binds selectively to an electrically conductive polymer comprising polypyrrole; and a linker joining together the first and second peptide binding domains; wherein selective binding means that the first and second peptide binding domains include a sequence from a peptide that is not removed during washing with Tris-buffered saline containing 0.1% (vol/vol) Tween-20 (0.1% TBS-T) while bound to the biomaterial or electrically conductive polymer.
