Poly-ethylene glycol induced super-diffusivity in lipid bilayer membranes

Thibault Tabarin, Aaron Martin, Robert J. Forster and Tia E. Keyes

Soft Matter, 8, 8743-8751 (2012)

Fluorescence lifetime correlation spectroscopy (FLCS) has been used to probe the influence of PEG-8000 on the fluidity of fluorescently labeled planar supported lipid bilayers on ozone plasma treated glass. The lipid membrane compositions examined were; DOPC, DOPC/DOPS (80/20 mol/mol) […]

Concentration dependence of the Flory (X) parameter within two-state models

V. A. Baulin and A. Halperin
Macromolecules, 35, 6432 – 6438 (2002)
The Flory χ parameter is typically assumed to depend only on the temperature, T. Experimental results often require the replacement of this χ(T) by χeff, which depends also on the monomer volume fraction, φ, χeff(φ,T). Such χeff(φ,T) can arise from two-state models, proposed for polyetheleneoxide (PEO) and […]
