Into the library: Screening a focused library of 259 peptide tweezers, composed of two identical arms with zero to three amino acids and an artificial anion recognition site, yielded DNA binders with nanomolaraffinity. These ligands are only modest gene carriers (transfection efficiency <10 %); however, excellent transfection efficiencies (up to 90 %) were achieved after the covalent attachment of
