organisms. likewise, the surface chemistry of biosynthesized nanoparticles still requires substantial understanding. As shown
in a few investigations [80, 85], the important role of metal resistance in an organism's ability to synthesize nanomaterials
would have significant potential to employ a rational approach for nanoparticle biosynthesis. Additionally, only recently
engineered organisms modified to over-express phytochelatins and metallothionein (that are known to bind to metal ions) have
been employed for the synthesis of a range of important nanomaterials [144], a strategy that requires serious investigation.
lastly, the commercial applicability for the large-scale synthesis of inorganic nanomaterials using a biosynthesis approach is
yet to be seen. An understanding of the important questions of the mechanism and surface chemistry will enable this approach
to be used on an industrial scale for the synthesis of inorganic nanomaterials.
