“…The interest in the study of protein-polyelectrolyte interactions is also driven by the new polyelectrolyte architectures, such as polyelectrolyte multilayers and polyelectrolyte-protein multilayers [10,11]. Mathew et al investigated [10] the adsorption of proteins (lysozyme and bovine serum albumin) on chitosan/PSS multilayer membranes.…”

“…[4][5][6]. If instead of a polyelectrolyte a protein is used, the formed complexes are commonly called protein-polyelectrolyte complexes [7][8][9][10][11][12][13][14]. Various experimental methods could be used for studying the formation and properties of such complexes.…”

“…PSS, the strong anionic counterpart do not respond to pH and is quite hydrophobic. These combinations are found in LbL coatings for the isolation of proteins, encapsulation of enzymes and other biomolecules. , The same pair also form effective multilayers for the removal of micro pollutants . Identical coating pH is maintained for the polyions so as to avoid the mutual influence on layer formation.…”

Microfiltration (MF) membranes with chitosan/polystyrenesulfonate (CHI/PSS) functional layer coated surface can act as a barrier against emerging contaminants (ECs) in water under low pressure. One (one bilayer) or two functional layers are enough for the removal of lidocaine (LD, 100%) and ibuprofen (IBU, >75%). The effect of various ions, surfactant and humic acid is studied along with the influence of feed pH. Phosphate interferes negatively with the removal efficiency of membrane for IBU and sulfamethoxazole (SMZ). The reusability of the membranes are illustrated by the desorption studies of LD. The extended life of membrane and hence the antifouling nature of the selected ECs indicate its potential in small scale filtration units. Effect of ionic strength in feed and in deposition medium on the rejection percentage is presented. This study shows that various mechanisms depending on the properties of ECs are responsible for the rejection of ECs.

“…[7] While PBS is an appropriate solution to simply simulate physiological conditions, which has been used for biomaterial applications for decades, [13] it contains a moderately high concentration of various salt ions, which may influence peptidesurface interactions. However, peptide-surface interactions are also important for a broad range of other areas of biotechnology [14][15][16][17][18][19] that may involve solution conditions more representative of pure water or aqueous solutions with much lower salt concentrations. This situation thus raises the important experimental question: How does the presence of salt ions influence peptide-surface interactions for these model systems?…”

Peptide-adsorption studies in the biomaterials field are typically performed in phosphate-buffered saline (PBS) to represent the physiological environment. However, the study of peptide adsorption in pure water or low-salt media (e.g., 10 mM potassium phosphate buffered water; PPB) is of interest for many other applications in the broader field of biotechnology. In previous studies we used surface plasmon resonance spectroscopy (SPR) and atomic force microscopy (AFM) to determine the standard state adsorption free energy of peptide adsorption (ΔG°ads) and the force required for peptide desorption (Fdes), respectively, for a wide range of surface chemistries in PBS and showed that these two parameters were strongly correlated. The objective of this present research was to repeat these studies in PPB rather than in PBS in order to determine the influence of the differences in salt concentration between these two environments and also to determine if the same correlation between ΔG°ads and Fdes held for peptide adsorption in PPB. The results from these studies show that ΔG°ads and the correlation between ΔG°ads and Fdes in PPB are not significantly different than in PBS for the evaluated set of peptide-surface systems.
