Salt-dependent properties of a coacervate-like, self-assembled DNA liquid

Liquid DNA droplets, made of self-assembled DNA particles (‘nanostars’), show salt-dependent viscosity, self-diffusion, and surface tension due mainly to basepairing thermodynamics. Yet, certain aspects indicate a heterogeneous liquid structure. These results are compared to other coacervate systems...

Zusammenfassung:Liquid DNA droplets, made of self-assembled DNA particles (‘nanostars’), show salt-dependent viscosity, self-diffusion, and surface tension due mainly to basepairing thermodynamics. Yet, certain aspects indicate a heterogeneous liquid structure. These results are compared to other coacervate systems.
