Abstract

A simple biotemplating method for the synthesis of silica (SiO2) and titania (TiO2) nanowires was designed on a fibrillar protein (alpha-synuclein) template. The diameter of SiO2 and TiO2 nanowires could be varied, between 20-100 nm, by varying the processing conditions. The nanowires were characterized by energy dispersive spectroscopy (EDS) and electron energy loss spectroscopy (EELS). Due to their high surface area and porosity, the nanowires were tested for potential applications in enzymatic biosensor design.

摘要

基于纤维状蛋白质（α-突触核蛋白）模板设计了一种用于合成二氧化硅（SiO₂）和二氧化钛（TiO₂）纳米线的简单生物模板法。通过改变加工条件，SiO₂和TiO₂纳米线的直径可在20至100纳米之间变化。通过能量色散光谱（EDS）和电子能量损失光谱（EELS）对纳米线进行了表征。由于其高表面积和孔隙率，对纳米线在酶生物传感器设计中的潜在应用进行了测试。
