Figure 3. — Activation of functional aptamers with isothermal re-association of shape-switching nanoparticles. (A) Schematics of isothermal re-association and re-assembly of aptamers. (B) Total EtBr and DFHBI-1T stained native-PAGE demonstrates fiber formation and aptamer activation on re-association of cognate cubes. (C) AFM images of the aptamer containing fibers. (D) Re-association and fiber formation can be traced by measuring fluorescence of DFHBI-1T in vitro. Error bars indicate s.d.; N = 3.
