“…This problem may be expected to be solved by the use of fluorophorelabeled amphiphiles, since this kind of fluorescence probe as part of the surfactant can take part in the formation of aggregates and provide more reliable information. Based on the considerations mentioned above, some fluorophore-labeled amphiphiles have been used to detect the correlative physical properties of various aggregates [20][21][22][23][24][25][26][27][28][29][30]. However, most of these studies focus on micelle [20][21][22][23][24] or membrane [25][26][27][28][29] systems.…”

“…It was clarified that SDS formed micelles together with the PVP polymer as a micelle-like aggregate in PVP/SDS solution. [20][21][22] For the ternary GMs with PVP K17 and PVP K30, the surfaces of probucol nanoparticles were probably covered by PVP-SDS micelle complex as a layered structure, so that ternary GMs with PVP K17 and PVP K30 were able to become stable in the suspensions. For the ternary GM with PVP K12, PVP K12 and SDS might not make a PVP-SDS complex with micelle-like structure, due to the shortest length of the chain (the molecular weight was 1/4 of PVP K17, 1/20 of PVP K30).…”

Pharmacokinetic profiles of probucol were evaluated after oral administration of the various nanosuspensions in rats. Probucol nanoparticles were prepared by co-grinding with various molecular weights of polyvinylpyrrolidone (PVP K12, PVP K17 and PVP K30) and sodium dodecyl sulfate (SDS). The average particle sizes of probucol after dispersing the ternary ground mixtures (GMs), probucol/PVP K12/SDS, probucol/PVP K17/SDS and probucol/PVP K30/SDS into water were 28, 75 and 89 nm respectively. The ternary GM suspensions with PVP K17/SDS and PVP K30/SDS were stable at 25°C. However the particle size of probucol from the ternary GM with PVP K12/SDS gradually increased. Pharmacokinetic profiles of probucol indicated that variation in particle surface condition covered with PVP and SDS in addition to the particle size affected the improvement of in vivo absorption of probucol. The ternary GM with PVP K12/SDS exhibited a superior improvement of probucol absorption compared to the GMs with PVP K17/SDS and PVP K30/SDS. The binary GM with PVP or SDS and physical mixtures with PVP and/or SDS did not show significant differences in the area under the plasma concentration-time curve compared to the unprocessed probucol. In conclusion, preparation of probucol nanoparticles by co-grinding with PVP K12 and SDS could be a promising method for bioavailability enhancement.

“…31 Condensation of oppositely charged surfactants onto polyelectrolyte chains is a well-studied phenomenon and is known to dramatically modify chain conformations. [32][33][34][35] A similar effect is likely to be responsible for the dramatic increase in the fluorescence intensity induced by backbone conformational modulation.…”

Poly(2-methoxy-5-[2′-ethylhexyoxy]-1,4-phenylenevinylene) (MEHPPV) derivatives with polyacrylic acid (PAA) chains grafted onto their backbone were found to be water soluble, and they exhibited a dramatic increase in their fluorescence intensity in the presence of a variety of surfactants, even at concentrations far below their critical micelle concentrations (CMC). This increase was accompanied by a blue-shift in the emission maximum. These observations are rationalized based on the postulate that the backbone conformation of the conjugated polymer is modulated upon interaction of the surfactant molecules with the polyelectrolytic tethers, which in turn results in a significant depletion of intra-chain interchromophore interactions that are known to cause red-shifted emission bands with significantly lower emission yields.
