It ' s well - known that nucleation consisted of homogeneous nucleation and heterogeneous nucleation . the organic matrix used as the template to induce inorganic crystal growth and simulate the biomineralization is actually to promote heterogeneous nucleation and inhabit homogeneous nucleation . urinary stone is a kind of product of unusual biomineralization 众所周知,结晶过程中的成核有均相成核和非均相成核两种可能,利用有机基质做模板,诱导无机晶体生长,模拟生物体内的矿化过程实际是促进非均相成核而抑制均相成核。

Biomineralization is a complicate process , which is difficult to study in the original situation inside the organism . to prophyl axis and cure of urinary stones , imitating the biomineralization out of the organism and studying the formation mechanism of urinary stone are very important to the health of human beings 由于生物矿化是一个复杂的过程,很难在体内原位对其进行模拟,利用体外模拟的方式探讨尿结石的形成机理,不仅对预防尿结石有重要意义,也更为无创治疗尿结石开辟了一条道路。

Soft - templates have particular characterizations . first , they have absolute advantage in simulating the progress of biomineralization since they were composed mainly by amphiphathic molecules ; second , the shape of soft - templates were versatile ; third , soft - templates were easy to construct and complex equipments were not needed . though soft - templates were not always controlled the crystal morphology and size strictly , they draw people ' s atte ntion by their characterization mentioned above 软模板的主要特点有: ( 1 )由于软模板大多是两亲分子形成的有序聚集体,它们的最大的特点是在模拟生物矿化方面有绝对的优势; ( 2 )软模板的形状具有多样性; ( 3 )软模板一般都很容易构筑,不需要复杂的设备。
