• nanoparticles, the interaction of mucin and DCX-loaded nanoparticle formulations was evaluated spectrophotometrically by turbidity measurements at 650 nm [10][14][79]. The basis of the experiment is to compare the absorbance of the mucin solution at 650 nm as a reference and the absorbance of the mixture of

• freshly prepared. Turbidity measurements were performed by adding 100 µL of the glycopolymer solution in HBS buffer to 500 µL of stock Con A solution. Final concentrations were 50 µM per mannose residue and 20 µM per Con A binding site, corresponding to a ratio Con A binding site/mannose = 1:2.5. The Con

• solutions containing additives such as polyallylamine, allylamine and others in the presence/absence of phosphate were investigated. The analyses are based mainly on turbidity measurements yielding information about the early aggregation steps which finally give rise to the formation and precipitation of

• silica. Keywords: phosphate; self-assembly; silica–polyamine interactions; silicomolybdic acid test; 29Si NMR; turbidity measurements; Introduction Long-chain polyamines (LCPAs) were previously found biomolecules that are tightly associated to the biosilica of various diatom species [1][2][3][4][5

• analysis of the influence of the polyamine structure and charge upon the polycondensation of silicic acid in the absence and presence of phosphate. The kinetics of the aggregation and silica polycondensation processes were studied by a combination of turbidity measurements and silicomolybdic acid test [31
