In a physiological environment, nanoparticles selectively absorb proteins to form 'nanoparticle-protein coronas', a process governed by molecular interactions between chemical groups on the nanoparticle surfaces and the amino-acid residues of the proteins. Here, we propose a biological surface adsorption index to characterize these interactions by quantifying the competitive adsorption of a set...

Competitive adsorption of the solute and the polar component of the mobile phase (the modifier) in reversed-phase liquid chromatography is discussed. Retention properties on surfaces differing in alkyl chain length (RP-18 compared with RP-8e) have been investigated. Typical solvent mixtures were used as mobile phases–methanol–water and acetonitrile–water. Three different types of compound were ...

adsorption and water treatment of ca (ii) and mg (ii) hardness were investigated via adsorption of metal ions onto commercial polyacrylic acid hydrogel beads as a novel sorbent for metal ions (ca2+, mg2+) removal and water treatment. batch equilibrium technique was carried out under the influence of solution ph, contact time, sorbent dosage, initial metal concentration and competitive study. th...
