title: Z-DNA recognition in B-Z-B sequences by a cationic zinc porphyrin.
abstract: For the first time it has been shown by spectroscopic studies such as circular dichroism and UV/Vis that cationic zinc porphyrin serves as a selective spectroscopic sensor that is able to recognize short left-handed Z-DNA tracts embedded in the B-Z-B sequences.
