DNA Origami

Caption

Scaffolded DNA origami utilizes numerous chemically synthesized, short DNA strands (staple strands) to direct the folding of a larger, biologically derived strand of DNA (scaffold strand). Molecular recognition (base pairing, i.e., A binds to T and G binds to C) directs the DNA to self-assemble into a specific structure as programed by the staple strand sequences. Unique staple strands produce a molecular pegboard with single-digit nanometer site-specificity precision. The atomic force microscopy image (right) demonstrates the final origami structure.
