基于肽包裹与超声处理程序的组合，首次从原材料中实现了水相中的单个硼纳米管（BNNT）的分离。原子力显微镜观察结果揭示了单个BNNT的代表性高度和长度。荧光和红外吸收光谱表明BNNT与肽之间存在强烈的PI-PI相互作用。 BNNT的最大吸收最大值从原始BNNT的200 nm显着蓝移到193 nm。用肽包裹对BNNT带隙的调节有望在各种纳米技术中的肽/BNNT复合物的潜在应用。
The isolation of individual boron nitride nanotubes (BNNTs) in aqueous phases has been achieved for the first time from raw materials based on the combination of peptide wrapping with a sonication procedure. Atomic force microscopic observations revealed the representative height and length of individual BNNTs. Fluorescence and infrared absorption spectra suggested the strong pi-pi interactions between BNNTs and the peptide. The absorption maxima of BNNTs were significantly blue-shifted from 200 nm for the original BNNTs to 193 nm. The modulation of the BNNT band gap with peptide wrapping promises potential applications of the peptide/BNNT complexes to various nanotechnologies.
