The thesis consists of six chapters. In the first, the technologies of atomic force microscopy and of the measurement elasticity of biomolecules were introduced. In the second, the validity of VSPFM was confirmed by lift mode atomic force microscopy. In this chapter, the height of DNA was measured by lift mode atomic force microscopy, which demonstrated that the method of height measurement of biomolecules by VSPFM was correct and established the foundation of the method of measurement elasticity of biomolecules by vibrating mode scanning polarization force microscopy. In the third chapter, detailed work has been illustrated on the foundation of the method of measurement elasticity of biomolecules by VSPFM. And the compressive elasticity of DNA was measured. In fourth and fifth chapters, the method was applied in the measurement elasticity of proteins. Two proteins elasticity, fibre-like protein α-synuclein and global protein IgG, were measured by VSPFM, through which the method wound its way to the application of biomolecules. In last chapter, the final part of the thesis was a summary. A conclusion of the thesis and a self-comment on my work as a PhD candidate have been made, and expectation about the further works has been addressed.

本论文共分为六章，第一章，引言部分主要介绍了原子力显微镜技术及生物大分子弹性测量技术；第二章主要是VSPFM方法的正确性论证，介绍抬高模式原理，利用抬高模式原子力显微镜对DNA的高度进行测量，论证振动模式扫描极化力显微镜测量生物大分子的高度的正确性以及准确性，从而为振动模式扫描极化力显微镜测量生物大分子的弹性方法的建立奠定基础；第三章以脱氧核糖核酸为例详细介绍了振动模式极化力显微镜测量生物大分子弹性的方法的建立，对DNA的压弹性进行了初步的测量和分析；第四章和第五章介绍了振动模式扫描极化力显微镜在蛋白质弹性测量中的应用：α-synuclein和IgG分别是纤维状蛋白和球状颗粒蛋白，通过振动模式扫描极化力显微镜测量这两种蛋白质的弹性，摸索振动模式扫描极化力显微镜在蛋白质弹性测量中的应用；第六章对全文进行了总结，在对论文的工作进行归纳和自我评价之后，还对进一步的工作进行了展望。
