DNA particle bonding (VIDEO)
Caption
The video shows that a blue particle initially binds to three red particles, satisfying its valence at room temperature. Upon heating, those bonds are broken, but upon cooling, the particle finds three red partners again, showing that the particle ‘chooses’ the number of bonds it makes. Their result implies that the DNA bonds between particles are reversible and rearrange on the particle surface to optimize valence.
