Fig. 3.5 Representation of a scheme of an experiment (upper set of drawings) and the obtained experimental results presented as AFM images (middle part) and cross-sectional profiles (bottom) that provides evidence of silica nucleation and shell formation on biopolymer macromolecules. Scheme of experiment. This includes the following main steps. 1. Protection of the mica surface against silica precipitation. It was covered with a fatty (ara-chidic) acid monolayer transferred from a water substrate with the Langmuir-Blodgett technique. This made the mica surface hydrophobic because of the orientation of the acid molecules with their hydrocarbon chains pointing outwards. 2. Adsorption of carbohydrate macromolecules. Hydrophobically modified cationic hydroxyethylcellulose was adsorbed from an aqueous solution. Hydrocarbon chains of polysaccharide served as anchors to fix the biomacromolecules firmly onto the acid monolayer. 3. Surface treatment by silica precursor. The mica covered with an acid mono-...

As noted, and as detailed in Table 2, a large variety of stationary-phase and mobile-phase factors influence the selectivity, recovery, and stability of proteins and other biomacromolecules in the adsorptive modes of HPLC. Batch adsorption pilot experiments provide an expedient approach to ascertain the effect of many parameters, such as the pH, nature, and concentration of organic solvent or ionic additives in the mobile phase, the temperature- or the static-binding capacity with a defined sorbent. Similarly, the influence of...

Adsorptive transfer stripping voltammetry (AdTSV) was introduced in 1986 as a new anal5 ical procedure based on the adsorptive pre-concentration of biomacromolecules on an electrode, the transfer of the adsorbed layer into a background electrolj e and subsequent voltammetric analysis [35]. The advantages of AdTSV were summarized as follows (i) the method utilizes differences in adsorbability of substances to their separation, (ii) due to their strong adsorption, analytes (oligonucleotides) can be separated from complex media, which are not suitable for voltammetric analysis of the conventional type, (iii) the interaction of biomacromolecules immobilized on the surface of the electrode with substances contained in the solution is possible, and (iv) all mentioned points can be affected by electrode potential [35].
