These examples span more than three decades, including novel biomimetic materials developments and the development of systematic if not systemic assays to evaluate the cytotoxic potential for emerging nanoparticulate materials applications. In addition, bioleaching and related biomaterials processing and processes were emerging along with biomimetics applied to materialsrelated innovations. This paper will review few research examplesor case historiesof biological issues and interdisciplinary applications in materials extraction, processing, and performance.
This paper illustrates some interdisciplinary, biological issues in materials science and engineeringstructure, properties, synthesisprocessing, and performance of materialscould find clear examples of biomaterials prostheses, artificial organs, biosensors, drug delivery, wound management, and plethora of medical equipment and devices.
Figure 1a, and illustrates variety of electron microscope views of this microorganism which utilizes CO2 as carbon source, and which requires sources of N^sub 2^ as well as phosphates for chemosynthesis and growth through energy derived from the catalytic oxidation of ferrous iron Fe^sup 2^, insoluble metal sulfides iron, copper, zinc, etc., or elemental sulfur. ferrooxidans, which becomes nonviable above about 40C. 9 Sulfolobus acidocaldarius and other thermophilic microorganisms have been isolated from acidic hot springs10,11 and other extreme environments. These and other examples provide compelling evidence and arguments for emphasizing biological sciences in materials science and engineering curricula.
ferrooxidans. 7,8 Biological systems and processes have had, and continue to have, important implications and applications in materials sciences and engineering.
These include metal extraction involving bacterial catalysis, galvanic couples, bacterialassisted corrosion and degradation of materials, biosorption and bioremediation of toxic and other heavy metals, metal and material implants and prostheses and related dental and medical biomaterials developments and applications, nanomaterials health benefits and toxicity issues, and biomimetics and biologically inspired materials developments. ferrooxidans is motile, singlepole flagellated, nonsporeforming, aerobic, chemiautotrophic, rodshaped, gramnegative bacterium. This paper illustrates some interdisciplinary, biological issues in materials science and engineering curricula.
