CTAB enhancement of FRET in DNA structures
Journal of Biophotonics, 2015The effect of cetyl‐trimethylammonium bromide (CTAB) on enhancing the fluorescence resonance energy transfer (FRET) between two dye‐conjugated DNA strands was studied using fluorescence emission spectroscopy and dynamic light scattering (DLS). For hybridized DNA where one strand is conjugated with a TAMRA donor and the other with a TexasRed acceptor ...

The interaction between morin and CTAB aggregates
Journal of Colloid and Interface Science, 2005Electronic absorption spectra, fluorescence emission spectra, ATR-FTIR spectra, cyclic voltammetric measurements, and ab initio quantum calculation are used to study the properties of morin in CTAB micelles with different microstructures and microenvironments and to gain information about the binding of morin with CTAB micelles. Morin can be located in

FTIR investigation of CTAB–Al–montmorillonite complexes
Spectrochimica Acta - Part A: Molecular and Biomolecular Spectroscopy, 2007In this study, CTAB-Al-montmorillonite complexes were synthesized by pre-modifying montmorillonite using different concentrations of surfactant (resulting in different surfactant loadings and basal spacings), then pillaring the organoclays with hydroxy-Al cations.

Combing DNA on CTAB-coated surfaces
Biophysical Chemistry, 2004A fluorescence microscope (FM) coupled with an intensified charge-coupled device (ICCD) camera was used to investigate the combing of DNA on cetyltrimethyl ammonium bromide (CTAB)-coated glass surfaces. DNA molecules can be combed uniform and straight on CTAB-coated surfaces. Different combing characteristics at different pH values were found. At lower

Ultrasonic Studies of Ctab in Glycol
Molecular Crystals and Liquid Crystals, 2003Ultrasonic absorption and velocity measurements have been made in cetyl trimethyl ammonium bromide (CTAB) in nonaqueous solution of ethylene glycol as a function of concentration, temperature, and at a fixed frequency. The interferometer technique has been used to measure ultrasonic velocity at 2 MHz.

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 1997
Abstract ESR spectroscopy was used in this study to monitor the aggregation behavior of cationic surfactant [cetyltrimethylammonium bromide (CTAB) in aqueous solution by measuring the rotational correlation time τ of a nitroxide labeled fatty acid probe (5-doxyl stearic acid) as a function of the surfactant concentration.

The effect of CTAB on Na2SO4 nucleation in mixed Na2SO4/CTAB aerosols by FTIR-ATR technology
Chinese Chemical Letters, 2016Abstract FTIR-ATR technology is used to study the efflorescence kinetic of Na2SO4 and mixed Na2SO4/CTAB aerosols. As the RH decreased linearly, the ν3 SO42− band shifts from 1094 cm−1 to 1132 cm−1, suggesting the phase transition of Na2SO4 from solution to crystal phase (III).

The dynamical landscape in CTAB micelles
Soft Matter, 2012Here we report molecular dynamics of cetyltrimethylammonium bromide (CTAB) based cationic micelles as studied using an incoherent quasielastic neutron scattering (QENS) technique. Data as obtained from two different spectrometers, IRIS at the ISIS facility, UK, and FOCUS at SINQ, PSI, Switzerland, having energy resolutions, ΔE ≈ 17.5 μeV and 55 μeV ...

Langmuir, 1999
The behavior of glycerol and glyceraldehyde as cosurfactants in the ternary CTAB/glycerol/water and CTAB/glyceraldehyde/water systems is studied. The phase diagrams only show the L and the hexagonal H1 phases. The L phase conductivity results at low surfactant concentration agree with no interaction between both cosurfactants and CTAB micelles.
