Binding behavior of DNA: A wormlike chain model is applied to determine the zero-force binding energetics of an intercalated DNA complex. A mono-intercalating agent is synthesized which can be very easily inserted into the DNA bases (see figure). This approach is particularly important in nuclear medicine and new radiation therapies.
