Assembly/Disassembly of DNA-Au Nanoparticles: A Strategy of Intervention
Scheme 1
A schematic diagram (not to scale) illustrating: (S1) the assembly and disassembly of DNA1-capped Au (A1) and DNA2-capped Au (A2) nanoparticles via a target DNA (T1) upon changing the temperature ( heat to 75–C; gradually cooling down to
C (RT)); and (S2) an intervention of the disassembly by the introduction of
P1 into the heated solution which leads to the formation of P2 upon returning
to room temperature.
