Attraction between DNA molecules mediated by multivalent ions

E.Allahyarov, G.Gompper, H.L\"owen

Multivalent ions induce tunable attraction between parallel DNA molecules that need not involve overcharging.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Multivalent ions induce a significant attraction between the DNA molecules whose strength can be tuned by the averaged valency of the ions.

C2weakest assumption

The primitive-model representation of DNA as rigid geometric shapes with uniform charge density is sufficient to capture the dominant physics of the effective force.

C3one line summary

Multivalent ions induce a significant, tunable attraction between DNA molecules that does not require overcharging and reverses with rising monovalent salt concentration.
