In this study, we developed a coarse-grained model based on the dissipative particle dynamics (DPD) method to investigate aggregates of cetyltrimethylammonium bromide (CTAB) molecules gold surfaces including nanoparticles. We adopted DPD for CTAB solutions by Mao et al. [Modeling aggregation ionic surfactants using smeared charge approximation in simulations. J Phys Chem B. 2015;119:11673–11683...

The interactions of β-lactoglobulin AB in the presence of cationic surfactants such as Cetyltrimethylammonium bromide and Cetyltrimethylammonium p-Toluenesulfonate have been investigated using a variety of experimental techniques such as conductivity, UV-Vis spectrophotometry and fluorimetry. The conductivity of surfactants aqueous solutions with β-lactoglobulin shows that the cmc of cationic s...

There are new chemical substances that increase the strength of washing products such as surfactants. However, these products are not biodegradable and can all be found in surface water, groundwater. Cationic surfactants are one of the pollutants of greatest danger to man is his environment. Therefore, we have determined some parameters of three cationic surfactants by molecular modeling, using...

In this present investigation, synthesis and characterization of mesoporous SiO2 was prepared the curcumin drug loaded into nanoparticles. The haemolytic study antibacterial activity were investigated. work is focused on silica by sol–gel methods from precursor tetraethyl orthosilicate (TEOS), NaOH, pore generating agent cetyltrimethylammonium bromide (CTAB). morphology analysis particles carri...

The electrochemical response of thyroxine (T4) at a carbon paste electrode (CPE) in the presence of cetyltrimethylammonium bromide (CTAB) was investigated. It gave a well-defined oxidation peak at 0.80 V and a sensitive reduction peak at 0.40 V. Compared with the indiscernible signal in the absence of CTAB, the reduction current of T4 at CPE was greatly enhanced in the presence of CTAB, due to ...

Formation of green coloured ternary complexes between palladium, chromeazurol S and cetyltrimethylammonium bromide or cetylpyridinium bromide is described over the pH range 4.6 to 5.6. The compositions, Pd(CAS)CTA2 and Pd(CAS)CP2 for the ternary complexes have been established by Job's method of continuous variations and by the mole ratio method using absorbance data. Strict control of experime...

Catanionic vesicles are supramolecular aggregates spontaneously forming in water by electrostatic attraction between two surfactants mixed in nonstoichiometric ratios. The outer surface charges allow adsorption to the biomembrane by electrostatic interactions. The lipoplex thus obtained penetrates the cell by endocytosis or membrane fusion. We examined the possible cytotoxic effects and evaluat...
