“…In recent years, there has been growing interest in the interactions between protein and surfactant due to their many applications in biosciences, foods and cosmetics, drug delivery, detergency and biotechnological processes. Using various numbers of tools and techniques, these interactions have been studied and published in the past few years (Goddard et al, 1993, Brash et al, 1995, Sonesson et al, 2008, Mehta et al, 2008, Verdes et al, 2008, Mehta et al, 2009. Cationic surfactants are widely used in industry and have a great bearing on our day-to-day life (Rosen, 1989).…”

Speed of sound, u, of dodecyltrimethylammonium bromide (DTAB) aqueous solutions has been determined at 295.15, 302.15 and 309.15 K. The speeds of sound, u, data have been used to estimate isentropic compressibility, K s , apparent molal isentropic compressibility, φ k(s), acoustic impedance, Z, molal sound of speed, R m , and relative association, R A , of DTAB in aqueous solution. These parameters have been interpreted in terms of solute-solute and solute-solvent interactions and micellar behavior of DTAB.

“…For the (C 12 Cys) 2 -BSA system the CAC/CMC ratio is 0.63 indicating a relatively weak interaction [17,29]. The difference between the CMC values in the presence and in the absence of protein can be used to determine the degree of binding of surfactant to protein, ˛, according to equation [17,50,51]:…”

“…A value of 1.50 has been referred for cationic surfactant DDAB [50]. The surfactant saturation binding is an important parameter that has been extensively studied [23,49,50,[52][53][54]. From dialysis studies Reynolds and Tanford [52] concluded that different proteins, with different molecular weights, bind identical amounts of surfactant, and reported a binding of 1.4 g of surfactant per gram of protein for the sodium dodecylsulphate (SDS)-BSA system in phosphate buffer solution (pH 6.7) and low ionic strength ( = 0.005).…”

“…Fluorescence of BSA is usually dominated by the contribution of its aromatic amino acid residues, namely tyrosine (Tyr), tryptophan (Trp) and phenylalanine (Phe), the emission of the latter one being negligible in most cases [26][27][28]50,57]. The variations in the fluorescence spectra obtained by exciting the protein at 295 nm have been attributed to the presence of tryptophan residues while the changes that result from protein excitation at 280 nm are associated with both tryptophan and tyrosine residues [26,28].…”

An amphiphilic fluorescent probe, 3‐dodecylamino dihydrogen imidazo[2,1‐α]benz[de]isoquinolin‐7‐one (compound 3), was used to sense the aggregate formation process of bovine serum albumine (BSA), sodium dodecyl sulfate (SDS) and their mixed system. The fluorescence intensity of 3 was significantly affected by the adding order of SDS and BSA, and SDS can be distinguished from other surfactants with the aid of BSA, but only when 3 is allowed to interact with BSA first. The results revealed that compound 3 is preferentially sited in the hydrophobic region of BSA, and thermodynamically in SDS‐BSA mixed aggregate. Sodium phosphate buffer solution (PBS) and BSA played important but distinct roles in distinguishing SDS micelle from the others.
