系统地介绍了仿生合成二氧化硅(SiO2)材料的研究进展,综述了仿生合成SiO2材料的模板分子特点及体外模拟方法,阐述了阴离子的存在、浓度、种类以及人工合成模板基质的不同类型对SiO2的尺寸和形貌的影响,并提出了新的实验思路,即设计合成具有催化活性的稳定的聚氨基酸多肽,在温和条件下,利用这种聚氨基酸多肽作为模板矿化SiO2材料,从而设计合成出具有特殊结构和性能的无机SiO2材料,并将此仿生材料应用到生物催化、药物载体等各个领域。
The research progress of biomimetic synthetic silica (SiO2) materials was systematically introduced. The template molecular characteristics and in vitro simulation methods of biomimetic synthetic SiO2 materials were reviewed. The existence, concentration and types of anions, as well as the different types of synthetic matrix substrates SiO2 size and morphology, and proposed a new experimental idea, that is, the design and synthesis of a catalytic activity of a stable polyamino acid polypeptide, under mild conditions, the use of this polyamino acid peptide as a template mineralized SiO2 material, which designed Synthesized with a special structure and properties of inorganic SiO2 material, and the biomimetic materials used in biocatalysis, drug carriers and other fields.
