| The property
of nucleic acids to recognize and specifically bind to
complementary sequence is the basis of DNA dendrimer
assembly. Polyprobe DNA dendrimers are assembled via
sequential hybridization of designed DNA components.
Pairwise hybridization of these strands results in the
formation of "monomers" which have 4 single
stranded "arms" and a double stranded
"waist". The outer surface of each layer has 2
types of single stranded arms. The molecular scaffolding
grows geometrically with each sequential layer of
hybridization. DNA dendrimers have been assembled ranging
in size from a few hundred bases (a 1-layer DNA
dendrimer) to several million bases (12-layer dendrimers) Continue |
