NanoScope软件上的力谱数据分析

The atomic force microscope (AFM) offers extraordinarily high resolution in force measurement applications, routinely yielding useful data down to the thermal noise floor of the cantilever, typically about 10pN. This along with the ease with which it is applied to many biological systems has made it a popular tool for studying such things as the specific interactions between biomolecules, the forces required to stretch polymeric molecules, and the forces that stabilize proteins. These sorts of applications have come to be collectively referred to as “force spectroscopy” applications.
