Title: Force spectroscopy 101: how to design, perform, and analyze an AFM-based single molecule force spectroscopy experiment. Author: Noy A. Journal: Curr Opin Chem Biol; 2011 Oct; 15(5):710-8. PubMed ID: 21862386. Abstract: Single molecule force spectroscopy presents a deceptively simple approach to probing interaction between molecules and molecular assemblies on the nanoscale by measuring forces that it takes to pull the molecules apart. Yet, a more detailed analysis reveals a wealth of different behaviors and interesting physics. This article aims to explore basic physical concepts behind these experiments from a strictly practical point of using these data to extract meaningful information about the interactions. It also focuses on different loading regimes in these experiments, different kinetics that they cause, and different data interpretation that is required for measurements in those regimes.[Abstract] [Full Text] [Related] [New Search]
