In nature, a few living organisms such as diatoms, magnetotactic bacteria, and eggs have developed specific mineral structures, which can provide extensive protection or unique functions. However, most organisms do not have such structured materials due to their lack of biomineralization ability. The artificial introduction of biomimetic-constructed nanominerals is challenging but holds great promise. In this overview, we highlight two typical types of mineral- living complex systems. One involves biological surface-induced nanomaterials, which produces artificial living-mineral core-shell structures such as the mineral- encapsulated yeast, cyanobacteria, bacteria and viruses. The other involves internal nanominerals that could endow organisms with unique structures and properties. The applications of these biomimetic generated nanominerals are further discussed, mainly in four potential areas： storage, protection, ＂stealth＂ and delivery. Since biomineralization combines chemical, nano and biological technologies, we suggest that nanobiomimetic mineralization may open up another window for interdisciplinary research. Specifically, this is a novel material-based biological regulation strategy and the integration of living organisms with functional nanomaterials can create ＂super＂ or intelligent nanoscale living complexes for biotechnological practices.

The formation of dipeptides from amino acids can be driven by hydroxyapatite at a relatively low temperature in air. For example, the formation of (Ala)2 from Ala is induced on hydroxyapatite at 110°C with considerable yield. Typically, condensing agents, high temperatures (>250°C) or high pressures (>25 MPa) are required to drive the condensation of amino acids. Similar effects are observed in the condensation of Gly, Glu and Asp. Experiments demonstrate that hydroxyapatite is an effective inorganic catalytic agent, reducing the activation barrier for the formation of dipeptides by more than 50%. HAP promotes condensation by adsorbing amino acid monomers in an organized manner, which decreases the distance between amino and carboxyl groups on neighboring molecules and extends the contact time of the reaction groups. This work provides a chemical understanding of the primitive condensation of amino acids and reveals a mechanism for enhancement of mineral catalysts. It is important that the conditions used for hydroxyapatite-assisted dipeptide formation are not harsh and can be readily achieved, revealing a possible mechanism for the chemical evolution of biomolecules over geologic ages.

Biological mineral generation via an amorphous precursor is a topic of great current interest. Various factors such as the temperature, solution composition and presence of organic molecules can influence this important inorganic process. Here we demonstrate that this mineral transformation can actually readily be regulated by solution viscosity, a fundamental but often overlooked property. In our experiment, amorphous calcium carbonate (ACC), a key model compound in biomimetic mineralization studies, is synthesized and dispersed into inert dispersants with different viscosities and the crystallization process is examined by using FT-IR spectroscopy and XRD. It is found that the inhibition of the transformation of ACC becomes more significant with increasing fluid viscosity. This phenomenon can be explained by the differences in ion diffusion in different media. Furthermore, the resulting crystals always have different morphologies and size distributions although they all have the calcite structure. This study implies that the importance of the fluid medium cannot be ignored in building a complete understanding of biological control of biomimetic crystallizations.

界面现象使物质在结晶过程中出现了临界现象。但最近的研究指出在物质溶解过程中 ,在表面能量的控制下也存在着临界现象以及尺寸效应。实验发现 ,当晶体自身小到一定的程度时 (通常在纳米尺度上并和临界蚀坑的大小相近 ) ,在溶解过程中其速度会自发降低 ,反应被抑制乃至停止。尽管在热力学上表面能的因素可以赋予小颗粒晶体较大的溶解度 ,但表面能却也能通过对临界条件的控制而使这些微粒在动力学上不被溶解。这个发现不仅解决了纳米颗粒在水溶液中稳定性的问题 ,而且还从动力学的角度解释了生物矿物选择纳米尺度作为其基本构成单元的原因。由于表面能和晶体生长溶解的动力学有着密切的关系 ,我们可以通过对表面能的调节来修改它们的动力学速度和晶体的形貌。反过来 ,也可以用动力学的方法来测定表面能及表面吸附脱附常数等。相对于常规的界面研究手段 ,通过生长和溶解动力学途径所得的数据有着很好的可靠性及重复性。我们认为 ,晶体生长和溶解的动力学和表面能的研究相结合 ,不仅为界面研究提供了新的思路和方法 ,而且也会推动晶体生长和材料科学的发展。
