This thesis addresses the development of a new force spectroscopy tool, correlation force spectroscopy (CFS) for the measurement of the properties of very small volumes of material (molecular to µm3) at kHz-MHz frequency range. CFS measures the simultaneous thermal fluctuations of two closely-spaced atomic force microscopy (AFM) cantilevers.  CFS then calculates the cross-correlation in the thermal fluctuations that gives the mechanical properties of the matter that spans the gap of the two cantilevers. The book also discusses development of CFS, its advantages over AFM, and its application in single molecule force spectroscopy and micro-rheology.
Milad Radiom received his PhD in Chemical Engineering at Virginia Tech in 2014, after MEng and BSc in Thermal and Fluids Engineering and Mechanical Engineering respectively from Nanyang Technological University and Amirkabir University of Technology. Thereafter, he was appointed as a postdoctoral research associate in Laboratory of Col...
