As previously indicated, many microorganisms produce EPS or slime, and several researchers have investigated the role of EPS in corrosion [86-88]. EPS consist of polysaccharides and proteins, plus significant amounts of nucleic acids, (phospho) lipids and humic substances [89-91]. The final composition of the EPS matrix results from a combination of the following active secretion, shedding of cell surface material, cell lysis, and/or adsorption of substances from the environment. EPS are usually acidic and contain functional groups, such as carboxylic and amino acids that, as mentioned earlier, readily bind metal ions. EPS can bind metal ions from the substratum or from a liquid medium and control interfacial chemistry at a metal/biofilm interface. EPS are also implicated in increased resistance of biofilm cells to biocides and other antimicrobial compounds [9].

A fatal drawback of organic interfacial materials is their insulating nature, or low electrical conductivity, which renders the solar cell performance highly sensitive to the thickness of the ECL. In fact, a comprehensive survey informs us that insulating organic ECLs usually play a positive role within 5-10 Unfortunately, it is very challenging to produce such... 

The ratio (p/G) has the units of time and is known as the elastic time constant, te, of the material. Little information exists in the published literature on the rheomechanical parameters, p, and G for biomaterials. An exception is red blood cells for which the shear modulus of elasticity and viscosity have been measured by using micro-pipette techniques 166,68,70,72]. The shear modulus of elasticity data is usually given in units of N m and is sometimes compared with the interfacial tension of liquids. However, these properties are not the same. Interfacial tension originates from an imbalance of surface forces whereas the shear modulus of elasticity is an interaction force closely related to the slope of the force-distance plot (Fig. 3). Typical reported values of the shear modulus of elasticity and viscosity of red blood cells are 6 x 10 N m and 10 Pa s respectively 1701. Red blood cells typically have a mean length scale of the order of 7 pm, thus G is of the order of 10 N m and the elastic time constant (p/G) is of the order of 10 s.
