摘要
为了深入认识竹材细胞壁的精细结构, 揭示竹材细胞壁的独特构造, 首次应用纳米红外技术(AFM-IR)研究竹材纤维细胞壁的化学成分及其分布, 探讨纳米红外技术在竹材细胞壁化学物质分布的研究方法。 结果表明, 利用纳米红外技术可以实现原位状态下对竹材纤维细胞壁的化学组成进行分析, 突破了传统红外光谱技术的衍射极限, 获得纳米级的红外光谱; 纳米红外技术采集的光谱与显微红外技术相比, 谱峰位置基本相同, 能正确反映竹材细胞壁的化学信息; 纳米红外技术是竹材细胞壁化学成分纳米分布的有效研究方法。
Abstract
Nano-IR technology was firstly employed on bamboo fiber research with purpose to further understand the fine structure of bamboo fiber cell wall. Chemical constituent distribution of bamboo fiber was studied, and the feasibility of the novel technology was discussed by comparing with other traditional methods. The results showed that Nano-IR technology, which has made a breakthrough on diffraction limit of traditional infrared spectroscopy, can acquire nano-scale infrared spectrum of bamboo cell wall in situ condition. The characteristic peak positions of Nano-IR spectrum is basically the same with that of microscopic FTIR spectrum, indicating that Nano-IR spectrum can reveal the chemical information of bamboo cell wall. The results of the present work suggested that nano-IR technology could be an effective research tool in research of nano chemical composition distribution of bamboo cell wall.
