Abstract

Sub diffraction limited infrared absorption imaging of hemoglobin was performed by coupling IR optics with an atomic force microscope. Comparisons between the AFM topography and IR absorption images of micron sized hemoglobin features are presented, along with nanoscale IR spectroscopic analysis of the metalloprotein.

摘要

通过将红外光学与原子力显微镜相结合，实现了对血红蛋白的亚衍射极限红外吸收成像。本文展示了原子力显微镜形貌和微米级血红蛋白特征的红外吸收图像之间的对比，以及对金属蛋白的纳米级红外光谱分析。
