Biopolymers advantages

Immobilized Enzymes. The immobilized enzyme electrode is the most common immobilized biopolymer sensor, consisting of a thin layer of enzyme immobilized on the surface of an electrochemical sensor as shown in Figure 6. The enzyme catalyzes a reaction that converts the target substrate into a product that is detected electrochemicaHy. The advantages of immobilized enzyme electrodes include minimal pretreatment of the sample matrix, small sample volume, and the recovery of the enzyme for repeated use (49). Several reviews and books have been pubHshed on immobilized enzyme electrodes (50—52). 

Owing to the weak hydrophobicity of the PEO stationary phases and reversibility of the protein adsorption, some advantages of these columns could be expected for the isolation of labile and high-molecular weight biopolymers. Miller et al. [61] found that labile mitochondrial matrix enzymes — ornitine trans-carbomoylase and carbomoyl phosphate synthetase (M = 165 kDa) could be efficiently isolated by means of hydrophobic interaction chromatography from the crude extract. 

In summary, besides its use as texturing additive, the combined functionality of GA is an advantage over other edible biopolymers that do not show antioxidant activities... 

All the aforementioned advantages and several additional features apply to ELP-based macromolecular carriers. First, ELP-based carriers are thermally responsive. Second, ELP is a biopolymer and therefore is nontoxic and biodegradable. Third, the gene-based synthesis of ELP allows the creation of genetic fusions with functional peptides and proteins, such as targeting sequences. 

TEOS is of considerable current use on an industrial scale owing to some advantages over sodium metasilicate. Limitations on the sol-gel processing with TEOS arise in the entrapment of biopolymers in silica. They are caused primarily by the alcohol that is separated in the course of precursor hydrolysis Equation (7). Most... 

Osmose plays an essential role in a wide technological and especially in biological systems represented by solutions of biopolymers. That is why understandable is interest of scientists to the problem of osmotic pressure of polymeric solutions which permits comparatively easy experimentally to determine the advantages and deficiencies of theoretical imaginations about thermodynamical properties of polymeric solutions.
