Light-Scattering Study of a Zwitterionic Polycarboxybetaine in Aqueous Solution

Amphiphilic Block Copolymers Based on Poly(2‐acryloyloxyethyl phosphorylcholine) Prepared via RAFT Polymerisation as Biocompatible Nanocontainers

“…Additionally, zwitterionic homopolymers show intra-as well as interchain interaction, depending on conditions such as the ionic strength of the solution. [39] All block copolymers prepared were analysed using dynamic light scattering after dissolving the polymers in methanol and diluting the solution with deionised water. Since the particle size can be influenced by the concentration, [36,40] all samples were measured at a constant concentration of 1 mg of polymer in 1 mL solution at 25 8C.…”

Effect of Surfactant and Various Salts on Aqueous Solution Properties of Naphthalene-Labeled Poly(hydrochloride-quaternized 2-norbornene-5-methylamine) made by Ring-Opening Metathesis Polymerization (ROMP)

“…[24] Previous reports also have thoroughly examined the difference in dilute aqueous solution properties such as viscosity, hydrodynamic diameter, cloud point, and the degree of binding. [25][26][27][28][29][30][31] These properties provide a reasonable assessment of the macroscopic behavior, however, a detailed analysis using a more sensitive characterization method is required. When naphthalene labels were incorporated into the water-soluble polymer, photophysical properties and the behavior of polymers in aqueous solution could be clearly defined.…”

Dual thermo- and light-responsive nanorods from self-assembly of the 4-propoxyazobenzene-terminated poly(N-isopropylacrylamide) in aqueous solution

“…Before UV irradiation, the <R g >/<R h > values of the micelles gradually decreased from 2.1 to 1.4 with raising temperature below LCST, while both the <R g > and <R h > decreased a little as shown in Figure 7 (B), because of intrachain contraction of thermo-responsive PNIPAM chains. 75 The lower value of <R g >/<R h > further confirmed that the collapsed PNIPAM chain became the denser shell in the core-shell micelle. After rather broad size distribution, which is close to the R h of particles in solution obtained by DLS analysis.…”
