Abstract Despite advancements in RNA extraction methods, from sources rich polyphenols and polysaccharides such as algae seagrasses remains a challenge. Here we present strategy using hexadecyltrimethylammonium bromide (CTAB) buffer demonstrate its effectiveness on broad range of red, green, brown algae, well the cyanobacterium Arthrospira platensis seagrass Zostera marina . For vast majority t...

In this paper, a novel membrane triiodide sensor based on a charge-transfer complex of (1,3-diphenyldihydro-1H-imidazole-4,5-dionedioxime) with iodine (CTCI) as a membrane carrier is introduced. The best performance was obtained with a membrane containing 30% polyvinylchloride (PVC), 63% dibutylphthalate (DBP), 5% CTCI and 2% hexadecyltrimethylammonium bromide (HTAB). The electrode shows a Nern...

OBJECTIVES To determine the mechanism of antimicrobial action for cationic lipid dioctadecyldimethylammonium bromide (DODAB) and hexadecyltrimethylammonium bromide (CTAB) against Candida albicans. METHODS Determination of DODAB or CTAB adsorption isotherms; cell viability; cell electrophoretic mobility (EM); and leakage of small phosphorylated compounds, proteins or DNA from fungus or haemogl...

In this study, the properties and adsorption behaviors of organoclays synthesized with two structurally different surfactants having same carbon chain length (hexadecyltrimethylammonium bromide (HDTMAB) benzyldimethylhexadecylammonium chloride (BDHAC)) were evaluated. The structural examined using Fourier-transform infrared spectroscopy, zeta potential analysis, X-ray diffraction, N2 adsorption...

Fluorescence quenching is a valuable tool to gain insight about dynamic changes of fluorophores in complex systems. Graphene (G), a single-layered 2D nanomaterial with unique properties, was dispersed in surfactant aqueous solutions of different nature: non-ionic polyoxyethylene-23-lauryl ether (Brij L23), anionic sodium dodecylsulphate (SDS), and cationic hexadecyltrimethylammonium bromide (CT...

The impact of hexadecyltrimethylammonium bromide (CTAB) on the separation of ds-DNA by capillary electrophoresis in conjunction with laser-induced fluorescence (CE-LIF) detection using poly(ethylene oxide) (PEO) solution is described. The use of CTAB for improved separation reproducibility and efficiency of DNA has not been demonstrated although it is widely used for controlling the magnitude a...

Nanoparticles of Zinc substituted Cobalt ferrite powders having general formula ZnxCo1-xFe2O4 (x = 0, 0.25, 0.5, 0.75, 1.0) have been produced by using analytical grade nitrates and hexadecyltrimethylammonium bromide (CTAB) as structure directing reagent via Chemical co-precipitation method. The morphology prepared polycrystalline nanoparticles were investigated X-ray diffraction (XRD), Fourier...

Abstract Dicarboxylic amino acid-based surfactants ( N -dodecyl derivatives of -aminomalonate, -aspartate, and -glutamate) in combination with hexadecyltrimethylammonium bromide (HTAB) form a variety aggregates. Composition concentration-dependent mixtures exhibit liquid crystal, gel, precipitate, clear isotropic phases. Liquid crystalline patterns, formed by surfactant mixtures, were identifie...

High pressure and high temperature (HPHT) conditions in geothermal wells have necessitated the need to develop thermally stable drilling mud systems combat potential complications. This is because fluids degrade under HPHT due effects. study therefore aims establish optimum concentration of a cationic surfactant that would successfully modify surface silica nanoparticles thereafter, evaluate pe...
