论文摘要
目的是两个方面：探索钻石同步基因红外线的能力，以包括近场光热微光谱（PTMS）；并迈向定量纳米组织学 - 使用同步加速器辐射（MU -FTIR）对硬皮病进行研究。随着AFM的最新进展，基于IR温度的系统在IR光束线上的集成仍然是一种有希望的和独特的方法。 PTMS独立系统具有钻石多模红外成像和微光谱光束线（MIRIAM）的这些初步测试在一个光束时间中取得了成功。据我们所知，这仍然是全球范围内很少的研究，这些研究设法将AFM抗性探针连接起来，以使用同步加速器辐射（SR）作为来源测量红外光谱。当对齐成功时，我们设法在强大的红外吸收器的样品上获得了良好的光谱。但是，无法一直保证对齐，并且信噪比变得太低，无法记录有关该提议科学兴趣的样品的任何有意义的光谱。我们阐明了PTMS仪器和数据采集所需的可能改进，以确保我们可以从非常薄的样品中收集足够的热信号。
The purpose was two-fold: To explore the capability of the Diamond Synchrotron infra-red so as to include near-field photothermal microspectroscopy (PTMS); and Toward a quantitative nanohistology - investigation of scleroderma using synchrotron radiation (mu- FTIR). With recent advances in AFM, the integration of an IR temperature-based system on an IR beamline is still a promising and unique approach. These preliminary tests of the PTMS stand-alone system with the Diamond Multimode InfraRed Imaging and Microspectroscopy beamline (MIRIAM) were successful in one beamtime. To our knowledge, this is still among very few studies worldwide that managed to interface an AFM-resistive probe to measure an infrared spectrum using synchrotron radiation (SR) as a source. When the alignment was successful, we managed to obtain good spectra on samples that were strong infrared absorbers. However, the alignment could not be guaranteed all the time, and the signal-to-noise ratio became too low to record any meaningful spectra on samples deemed of scientific interest for this proposal. We clarified the possible improvements to PTMS instrumentation and data acquisition needed to ensure that we can collect sufficient thermal signals from very thin samples.
