Two strands of DNA will bind most strongly to each other if their base sequences are complementary. The specificity of this molecular recognition property makes DNA a versatile material for use in the assembly of complex nanostructures. The free energy of hybridization, released as two DNA strands come together to form double-stranded DNA, can be used to induce nanostructures to perform mechanical work. Strand displacement allows one to operate such structures as cyclic engines. DNA can thus serve both as a structural material and as a fuel to power the nanoworld.
Coffee and cookies before the presentation at 3:50 pm, and refreshments after the presentation will both be served in Room 128.
