title: Towards a circular bis-peptide nucleic acid.
abstract: En route to a circular bis-PNA molecule, we have synthesized and characterized the DNA binding of several "clamp"-type bis-PNAs. In order to incorporate charge into a circular PNA, a new linker based on the achiral 2-aminoethylglycine has been used.
