As indicated above, the development of bio-nanohybrids by mimicking biomineralization represents an extraordinarily useful approach. This is, for instance, the case for those bio-nanocomposites based on bone biomimetic approaches, which show excellent structural properties and biocompatibility. They are prepared by...

As mentioned earlier, biological systems have developed optimized strategies to design materials with elaborate nanostructures [6]. A straightforward approach to obtaining nanoparticles with controlled size and organization should therefore rely on so-called biomimetic syntheses where one aims to reproduce in vitro the natural processes of biomineralization. In this context, a first possibility is to extract and analyze the biological (macro)-molecules that are involved in these processes and to use them as templates for the formation of the same materials. Such an approach has been widely developed for calcium carbonate biomimetic synthesis [13]. In the case of oxide nanomaterials, the most studied system so far is the silica shell formed by diatoms [14].

In this chapter, we will introduce a bioinspired approach to biomineralization. First, a fundamental concept of the bioinspired approach is compared with the biomimetic approach. Here is a question, What is a bioinspired approach If we want to fly in the sky, when we look at flying birds what do we have to do Two kinds of typical answer were considered, as shown in Figure 6.4. One is Bird-Man, in the Edo period (AD 1600) in Japan, a man named Kokichi attempted to fly. He wore wide, large wings on both his arms, and fluttered his arms vigorously, but in vain. This is a typical biomimetic approach. He only mimicked the style of a flying bird, so his innovative idea ended in failure.

Studies of biominerals and biomineralization have various applications, from biology to biomimetics. 

The era of biomimetic peptide- and sugar-based polymer vesicles has just begun and seems very promising. Bioinspired vesicles are mainly applied for drug deliv-ery/release and the fabrication of composite materials, but could readily be used for biomimetic materials science, biomineralization, and so on. Especially interesting are smart vesicles changing properties in response to an external stimulus (temperature, pH, ions).

Coordination as the Motif in the Rational Design of Supramolecular Metallacyclic Polygons and Polyhedra this issue will be expanded later in the Chapter. And since most heteromacrocycles have unique shape and form, Ozin s Accounts article entitled Morphogenesis of Biomineral and Morphosynthesis of Biomimetic Forms adds a macroscopic dimension to macrocyclic chemistry <97ACR17>.
