WebNov 10, 2014 · The FRET results are consistent with the average shape of the PEG polymer as a sphere of Flory radius in an aqueous medium. Indeed, after normalization against the FRET efficiency of PEG 88, the measured FRET efficiencies of PEG polymers matched closely with the ones calculated based on the Flory radii of the polymers . It should be … WebMar 9, 2016 · As SAWs cannot be calculated analytically, the Flory theory is used as an approximation to find the radius of gyration of a real polymer in free and confined spaces . According to this theory, the interplay between the interaction energy, \(_{ }F_{int} \) , and the entropic energy, \(F_{ent} \) , determines the equilibrium configuration of the ... rqt tf_tree

WebThe mushroom regime is often invoked when s is greater than twice the Flory radius R F of the polymer (s > 2R F ) while the brush regime is encountered when s < 2R F [9] (see Figure 8). The Flory ... WebJul 3, 2007 · In particular, in the limit of strong fields θ ⪢ 1 the average Flory radius R F is found to saturate to its minimal value, which is calculated as a function of the excluded volume parameter u. This finding is in distinct contrast to the result for the Flory radius R F in the case of ideal polymers where R F approaches zero as the interaction ...
