Our objective is to characterize the nanoscale properties and function of polymer surfaces and inorganic nanomaterials used for various applications. Our characterization technique combines the use of AFM and apertureless near field scanning infrared microscopy (ANSIM), but the tunability of our laser is limited. By incorporating the laser whose purchase is proposed herein, we will be able to extend our spectral sensitivity into the critically important fingerprint region of the infrared.

我们的目标是表征用于各种应用的聚合物表面和无机纳米材料的纳米级特性和功能。 我们的表征技术结合了 AFM 和无孔径近场扫描红外显微镜 (ANSIM) 的使用，但我们的激光器的可调谐性有限。 通过合并本文建议购买的激光器，我们将能够将我们的光谱灵敏度扩展到至关重要的红外指纹区域。
