Biomolecular condensates are viscoelastic materials. Here we investigate the determinants
of the sequence-encoded and age-dependent viscoelasticity of condensates formed by the …

Depending on conditions such as the mixing ratio, speed and order of addition, and ionic
strength, when solutions of oppositely charged polyelectrolytes are mixed, the stoichiometry …

Charge-carrying species, such as polyelectrolytes, are vital to natural and synthetic
processes that rely on their dynamic behavior. Through single-particle tracking techniques …

Spontaneous phase separation, or coacervation, of oppositely charged macromolecules is a
powerful and ubiquitous mechanism for the assembly of natural and synthetic materials. Two …

Ionically conductive polymers are commonly made of monomers containing high polarity
moieties to promote high ion dissociation, like poly (ethylene oxide)(PEO), polyvinylidene …

Polymer chain diffusion within a hydrated polyelectrolyte complex, PEC, has been measured
using an ultrathin film format prepared by the layer-by-layer method. Isotopically labeled self …

Polyelectrolyte complexes (PECs) have attracted considerable attention owing to their
unique physicochemical properties and potential applications as smart materials. Herein …

We utilize single particle tracking studies to investigate the diffusion of polylysine through
concentrated matrices of cationic polylysine and anionic polyglutamic acid with no added …

Strong changes in bulk properties, such as modulus and viscosity, are observed near the
glass transition temperature, T g, of amorphous materials. For more than a century, intense …

Biomolecular condensates that form via phase separation coupled to percolation are
complex viscoelastic materials whose properties are thought to influence cellular functions …
