A colorimetric strategy based on conjugated polyelectrolyte aggregates has been applied to determine and distinguish anionic, cationic and non-ionic surfactants.

The increasing death rate caused by drug overdose points to an urgent demand for the development of novel detoxification therapy. In an attempt to detoxify tricyclic antidepressant overdose, we prepared a lipid nanoemulsion, called squarticles, as the nanoantidote. Squalene was the major lipid matrix of the squarticles. Here, we present the animal study to investigate both the pharmacokinetic a...

The distribution of anionic binding sites has been investigated in the isolated Golgi complex using cationic ferritin. The greatest density of anionic sites occurs on the tubular network and small vesicles, and this binding is accompanied by increased levels of galactosyltransferase activity. The density of anionic sites on the cisternae is less than on the tubules and shows anisotropic distrib...

At pH 7 the bacteriophages T1 and T2 attach to anionic exchangers when suspended either in distilled water or in salt solutions. They attach to cationic exchangers only in the presence of salt. T2 requires approximately ten times higher a salt concentration than does T1 virus, a relationship which is duplicated in the attachment of these phages to their common host cell, E. coli B. The host cel...

We report physical adsorption of highly anisotropic copolymer worms with either anionic or cationic charge onto planar silica, cellulose nanocrystal nanofibril surfaces using a quartz crystal microbalance dissipation monitoring.

this paper presents a systematic study of the surface chemistry, porous texture and adsorptive characteristics of prepared new activated carbon using persian mesquite grain. several techniques and methodologies such as, proximate analysis, n2 adsorption–desorption isotherms, scanning electron microscope (sem), fourier transform infrared spectroscopy(ft-ir), x-ray diffraction (xrd), x-ray photoe...

alpha-amylase e.c.3.2.1.1. (1,4 glucan, 4 glucanohydrolase) can be obtained from salivary glands, pancreas and microorganisms such as pseudomonas and asperigllus, as well as muscles and ovarian tubes.1.2 alpha-amylase from bacillus subtilis #1024(a tcc 465)* was purified with a highest degree of purity in our laboratory (31.59 u/mg). the extracellular alpha-amylase was subjected to different pu...

The progresses of understanding of the surfactant adsorption at the hydrophilic solid-liquid interface from extensive experimental studies are reviewed here. In this respect the kinetic and equilibrium studies involves anionic, cationic, non-ionic and mixed surfactants at the solid surface from the solution. Kinetics and equilibrium adsorption of surfactants at the solid-liquid interface depend...

In this work needle like hydroxy apatite were synthesized in a reverse microemulsion droplets of water in cyclohexane, separated by a cationic surfactant and co-surfactant, in the presence of Na-polyacrylate (PAA) as an anionic polyelectrolyte. Characterization of the as formed HAp nanoparticles at the room temperature were carried out by X-ray diffraction (XRD) and Fourier transform infrared s...
