Abstract
Mixed micelles formed from nonionic surfactant Triton X-100 (TX100), anionic surfactant sodium dodecyl dioxyethylene sulfate (SDP2S), and triblock copolymer Synperonic L61 (SL61) were investigated by 1H NMR spectroscopy. The size and shape of the aggregates were determined by diffusion ordered NMR spectroscopy (DOSY), while 2D nuclear Overhauser enhanced spectroscopy (NOESY) NMR was used to study the mutual spatial arrangement of the surfactant molecules in the aggregated state. An average micellar hydrodynamic radius of 3.6 nm, slightly increasing upon increasing TX100 molar fraction, was found for the mixed systems without additives. Addition of SL61 to the mixed micellar systems results in a slight increase of micellar radii. In the presence of AlCl3, an increase of TX100/SDP2S micellar sizes from 4 to 10 nm was found when increasing the SDP2S molar fraction. The mixed TX100/SDP2S micelles in the presence of both AlCl3 and polymer SL61 are almost spherical, with a radius of 4.5 nm. 2D NOESY data reveal that, as the individual TX100 micelles, mixed TX100/SDP2S and TX100/SDP2S/SL61/AlCl3 micelles also have a multilayer structure, with partially overlapping internal and external layers of TX100 molecules. In these mixed micelles, the SDP2S molecules are located at the level of the external layer of TX100 molecules, whereas the SL61 polymer is partially incorporated inside of the micellar core.

Abstract
The development of neutron reflectometry has transformed the study and understanding of polymer/surfactant mixtures at the air/water interface. A critical assessment of the results from this technique is made by comparing them with the information available from other techniques used to investigate adsorption at this interface. In the last few years, detailed information about the structure and composition of adsorbed layers has been obtained for a wide range of polymer/surfactant mixtures, including neutral polymers and synthetic and naturally occurring polyelectrolytes, with single surfactants or mixtures of surfactants. The use of neutron reflectometry together with surface tensiometry, has allowed the surface behaviour of these mixtures to be related directly to the bulk phase behaviour. We review the broad range of systems that have been studied, from neutral polymers with ionic surfactants to oppositely charged polyelectrolyte/ionic surfactant mixtures. A particular emphasis is placed upon the rich pattern of adsorption behaviour that is seen in oppositely charged polyelectrolyte/surfactant mixtures, much of which had not been reported previously. The strong surface interactions resulting from the electrostatic attractions in these systems have a very pronounced effect on both the surface tension behaviour and on adsorbed layers consisting of polymer/surfactant complexes, often giving rise to significant surface ordering.

Abstract
The addition of electrolyte (0.1 M NaCl) is shown to have a significant impact upon the surfactant concentration and solution pH dependence of the adsorption of sodium dodecyl sulfate (SDS)/polyethyleneimine (PEI) complexes at the air-solution interface. Substantial adsorption is observed over a wide surfactant concentration range (from 10(-6) to 10(-)2 M), and over much of that range of concentrations the adsorption is characterized by the formation of surface multilayers. The surface multilayer formation is most pronounced at high pH and for PEI with a lower molecular weight of 2K, compared to the higher molecular weight of 25K. These results, obtained from a combination of neutron reflectivity and surface tension, highlight the substantial enhancement in surfactant adsorption achieved by the addition of a combination of the polyelectrolyte, PEI, and a simple electrolyte. Furthermore the effect of electrolyte on the pH dependence of the adsorption further highlights the importance of the hydrophobic interaction in surface surfactant/polyelectrolyte complex formation.

Abstract
This paper describes how the cationic polyelectrolyte, polyDMDAAC (poly(dimethyl diallylammonium chloride)), is used to manipulate the adsorption of the anionic surfactant SDS and the mixed ionic/nonionic surfactant mixture of SDS (sodium dodecyl sulfate)/C(12)E(6) (monododecyl hexaethylene glycol) onto the surface of hydrophilic silica. The deposition of a thin robust polymer layer from a dilute polymer/surfactant solution promotes SDS adsorption and substantially modifies the adsorption of SDS/C(12)E(6) mixtures in favor of a surface relatively rich in SDS compared to the solution composition. Different deposition conditions for the polyDMDAAC layer are discussed. In particular, at higher solution polymer concentrations and in the presence of 1 M NaCl, a thicker polymer layer is deposited and the reversibility of the surfactant adsorption is significantly altered.

Abstract
Two polymer-surfactant mixtures have been studied at the air-water interface using neutron reflectivity and surface tension techniques. For the noninteracting system poly(N-isopropylacrylamide) (PNIPAM)/octaethyleneglycol mono n-decyl ether (C10E8), the adsorption behavior is competitive and driven purely by surface pressure (pi). When pi(polymer) > pi(surfactant), the surface layer consists of almost pure polymer, and for pi(polymer) < pi(surfactant), the polymer is displaced from the surface by the increasing pressure of the surfactant. Beyond the CMC, the polymer is completely displaced from the surface. For the interacting system PNIPAM/sodium dodecyl sulfate (SDS) where the two species interact strongly in the bulk beyond the critical aggregation concentration (CAC), the surface behavior is more original. Earlier neutron reflectivity studies investigated PNIPAM adsorption behavior where the SDS was contrast-matched to the solvent. In the present study, complementary measurements of SDS adsorption where PNIPAM is contrast-matched to the solvent give a complete view of the surface composition of the mixed system. At a constant polymer concentration, with increasing SDS, three main regimes are obtained. For C(SDS) < CAC, adsorption is governed by simple competition and PNIPAM is predominant at the interface. At intermediate SDS concentration (CAC < C(SDS) < x2, where x2 indicates the predominance of free SDS micelles), interfacial behavior is governed by bulk polymer-surfactant interaction. Adsorbed polymer is displaced from the interface to form PNIPAM-SDS complex in the bulk. SDS adsorption remains weak since most of the SDS molecules are used to form bulk polymer-surfactant aggregates. Further increase in SDS concentration results in continued displacement of PNIPAM and an abrupt increase in SDS adsorption. This is a result of saturation of bulk polymer chain with adsorbed micelles. Interestingly, beyond x2, PNIPAM is not completely displaced from the surface. A mixed PNIPAM-SDS adsorbed layer with enhanced packing of the SDS monolayer is formed.

Abstract
The interaction of polyvinylpyrrolidone (PVP) with an anionic surfactant (sodium dodecyl sulfate, SDS), a nonionic surfactant (pentaethylene glycol monodecyl ether, C(10)E(5)), and a zwitterionic surfactant (lauryl amido propyl betaine, LAPB) has been investigated by means of pulsed gradient spin-echo NMR (FT-PGSE NMR), allowing self-diffusion coefficients to be determined. The results confirm the strong interaction prevailing in the PVP/SDS system, whereas no association has been observed in the PVP/C(10)E(5) and PVP/LAPB systems. Mixing PVP with two surfactants, namely SDS and C(10)E(5) or SDS and LAPB, results in the formation of ternary aggregates between the polymer and the mixed micelles. Copyright 2001 Academic Press.

Abstract
In the past several years, atomic force microscopy (AFM) has provided topographic images of adsorbed plasma proteins in situ at unprecedented resolution. Imaging has been limited to adsorbed protein on relatively smooth model substrates such as mica, graphite, or self-assembled monolayers on which the small height of the protein can be observed from the background. The inherent roughness of biomaterial surfaces has prevented observation of adsorbed proteins in topographic images. We report imaging isolated fibrinogen molecules adsorbed on National Heart Lung and Blood Institute (NHLBI) reference materials polydimethylsiloxane and low-density polyethylene in situ using phase imaging AFM. Fibrinogen, a plasma protein important for blood coagulation and platelet aggregation, was adsorbed from dilute solution onto reference biomaterial surfaces at sub-monolayer coverage. Tapping mode AFM was used to image the samples. For polydimethylsiloxane, the lateral size of the surface features is much greater than the dimensions of proteins. This allowed adsorbed proteins to be observed in topographic images. The phase imaging signal of tapping mode AFM provides information on differences in material properties of the surface, and was used to distinguish individual protein molecules from the underlying polymer surface. On the low-density polyethylene surface, characteristic topographical features are of the same magnitude as the protein molecules, so that protein cannot be distinguished from the surface using topographic images. However, phase images were used to successfully locate and characterize the distribution of the protein. Phase imaging was not able to distinguish fibrinogen adsorbed onto expanded polytetrafluoroethylene. The utility and limitations of the phase imaging technique for characterizing protein adsorption to rough surfaces is discussed.
