To summarize, maximal adsorption of glucose in combination with BSA on the surface of ultra-fine silica was appreciably less than that of fructose under the same conditions. On the other hand, the positive bio-effect of glucose-containing composites is much higher for both reproductive cells and erythrocytes.

Table 12 shows the molecular size of some biological macromolecules for comparison to the mean pore size of the resins. When selecting the pore size of a resin for the recovery or immobilization of a specific protein, a general rule is that the optimum resin pore diameter should be about 4 to 5 times the length of the major axis of the protein. Increasing the pore size of the resin beyond that point will result in decreases in the amount of protein adsorbed because the surface area available for adsorption is being decreased as the pore size is increased. An example ofthis optimal adsorption of glucose oxidase, as defined by enzyme activity, is shown in Fig. Enzyme... 

An Eley-Rideal mechanism, characterised by the adsorption of glucose in its hydrated form on gold with equilibrium constant Kq, followed by reaction with oxygen coming from the Uquid phase, according to Eqs. (13.4)-(13.7), can justify the result.

The electrochemical oxidation of glucose has been reviewed (49 refs.). Special attention was given to the effect of the electrode material on the process, and to the adsorption of glucose and its oxidation products on the electrode surface. The oxidation of glucose with single-crystal platinum electrodes in different orientations has been studied. Pronounced stmctural sensitivity of the reaction was discovered, the Pt(lll) and its vicinal surfaces being the most active. ...
