Magnetite Biomineralization - Research Paper Examplent study showed that most human brain tissues had a least(prenominal) five million single domain crystals per gram and in excess of 100 million crystals per for dura and pia. The crystals were in clumps of 50-100 particles. During biologically controlled mineralization of magnetite the organism makes wont of cell activities to control the nucleation, growth, final place of deposit, and the morphology of the mineral. The process of biomineralization of magnetite commonly numbers in an isolated environment. The nucleation and growth of biominerals is dependent on the existence of a localized zone that enjoys and maintains adequate supersaturation. The two phases of iron that commonly feature in the process of magnetite biomineralization in bacteria be ferrihydrite and magnetite. In bacteria, magnetosome cell organ is responsible for producing magnetite. The organelle is basically a biomineralized greigite or magnetite.Magnetite F e3O4 is a naturally occurring mineral. Scientists job that the mineral is one of the most magnetic minerals that naturally occur on earth. Research has shown that magnetite does not only occur naturally on the earth, it is also found in animal tissues. Indeed scientists note that nearly all groups of organisms form one form or another of biominerals. Some of the organisms that have been found to precipitate magnetite include arthropods, chordates, and mollusks. Recent studies show that biominerals are found in humans such as in bones and teeth. The precipitation of magnetite in living organisms occurs through the biomineralisation process. This paper will debate Magnetite biomineralization in light of its chemistry, occurrence, and crystallography among other issues.Biomineralisation or biologically regulated mineralization is basically the process through which living organisms produce minerals according to Kirschvink and Hagadorn (2000). Weiner and Dove (2013) note that biomine ral products are composites that comprise both organic and mineral
