Extensive review literature exists in the area of biological fuel cells. Notably, Palmore and Whitesides summarized biological fuel cell concepts and performance up to 1992." More recently, Katz and Willner discussed recent progress in novel electrode chemistries for both microbial and enzymatic fuel cells,and Heller reviewed advances in miniature cells.This article does not duplicate these valuable contributions. Instead, we focus on the strengths and weak-... 

Cells. We finally come to what are the direct building blocks of biological materials cells. Cells are assemblies of molecules enclosed within a plasma membrane that carry out specific functions. The human body contains over 10 " cells, all of which take in nutrients, oxidize fuels, and excrete waste products. Despite their varied functions, all cells have a similar internal organization. We will concentrate on this internal organization for now and will leave the topics of cell reproduction, energy production, and related concepts to the molecular biologist.

There seems to be no explicit proposal for the most widely held hypothesis for the persistence of mitochondria genomes, but the hypothesis is implicit in many discussions of mitochondrial structure and function. For example, and in contrast to the open question posed by Alberts et al., Cell and Molecular Biology Concepts and Experiments (Karp 2002) provides what is probably still the current consensus view.

Peptides are also useful tools to demonstrate the validity of the biological concept and thereby show that the inhibition of the selected protein-protein interaction leads to the expected phenotype. Since peptides generally have a low bioavailability, they often have to be coupled to special sequences that facilitate their transport into cells [23]. Finally, the peptides can serve as starting points for a drug discovery programme. They can be transformed to peptidomimetics that - in some cases - can be further depeptidized.

Bionic Manufacturing System The Bionic Manufacturing System transfers biological concepts into a manufacturing system. The autonomy and spontaneity are the dominant characteristics. Each entity is considered to be a cell, which is differentiated by a function each cell is able to perform multiple operations and could be combined with different cells (Tharumarajah et al. 1996).

Electron microscopy is often used to examine biological specimens and other materials on a magnification level that cannot be approached by light microscopy. Microscopists typically have a bachelor s degree in biology and have taken courses in cell and molecular biology concepts, as well as in the principles and techniques of electron microscopy, including specimen preparation and research methods.

Electron microscopy has contributed more than any single method to the development of biological concepts if only by revealing the existence of unknown cellular structures, and particularly, the extensive array of membrane systems cells contain. By providing methods for the observation and identification of specific membrane systems, electron microscopy has helped considerably in the isolation of such systems and the supply of pure preparations for use in countless biochemical studies. 

Cell separation techniques that use an inward flow component are referred to as countercurrent separation techniques. The concept of countercurrent separation is compHcated by biological variations of all parameters in equation 4.
