Biological liquids

A lot of natural as well as technological objects of analytical control are colloidal systems, i.e. human blood, biological liquids, sol and suspension forming in different technological processes (ore-dressing, electrochemical deposition, catalysis and other), food, paint-and-lacquer materials, sewage water and other.

Electrochemical biosensors based on detection of hydrogen peroxide at platinized electrodes were found to be more versatile allowing a decrease in detection limit down to 1 i,mol L 1 [109]. However, all biological liquids contain a variety of electrochemically easily oxidizable reductants, e.g. ascorbate, urate, bilirubin, catecholamines, etc., which are oxidized at similar potentials and dramatically affect biosensor selectivity producing parasitic anodic current [110].

On the opposite side, the small attacks repeated by a very concentrated irritant can accumulate microlesions that could be quite severe in the end. For instance, the more we concentrate a weak acid such as acetic acid, the more aggressive we make it. The icy acetic acid is a strong corrosive because it is moreover totally anhydride. When in contact with cellular biological liquids, it literally pumps all the water and provokes a necrosis of tissues. 

Intrinsic Interfacial Free Energies of Biological Liquids... 

Thus it would seem that the actual intrinsic surface tension of biological liquids, i.e. the one that plays a role in the interactions between cells among one another, and between cells and biopolymers, must be close to that of serum or plasma ultrafiltrates, i.e. y 70 dyn/cm or the intrinsic interfacial free energy of the interstitial mammalian liquid, serum or plasma, or AF —140 ergs/cm2. 

Current methods used to measure antioxidant activity are complicated, expensive, time-consuming, and as a rule, cannot be used for continuous monitoring. Potentiometry with the use of a mediator system and nanoparticles containing electrodes provides a very simple express-method for measuring antioxidant activity of biological liquids, nutrients, drugs and foodstuffs. 

Competitive enzyme-linked immunosorbent assay provides an alternative to dual-antibody sandwich enzyme-linked immunosorbent assay and is widely used for the measurement of substances in biological liquids. 

In addition to Section 6.07.4.2 it should be noted that the chromatographic determination of irbesartan 83 in biological liquids has been developed <2007JC(B)245>. A selective thin layer chromatographic method implies a complexation of 1 //-tetrazole and 1-methyltetrazole to Co(n) ions on a TLC plate followed by a subsequent oxidation of Co(ll) by permanganate has been presented <2007JC(A)145>.
