Designer’s toolkit for dynamic DNA nanomachines: Arm-waving nanorobot signals new flexibility in DNA origami

Researchers have demonstrated a new approach to joining — and reconfiguring — modular DNA building units, by snapping together complementary shapes instead of zipping together strings of base pairs. This not only opens the way for practical nanomachines with moving parts, but also offers a toolkit that makes it easier to program their self-assembly. …read more
