DNA dendrimers with two, three, six, nine or 27 arms were reassociated as complementary pairs in solution or with an array of complementary oligonucleotides on a solid support. In all cases, duplex stabilities were greater than those of unbranched molecules of equal length. A theoretical treatment for the process of dissociation of dendrimers explains the major properties of the complexes. The favourable features of DNA dendrimers-their enhanced stability and the simple predictability of thei...Expand abstract
