An experimental investigation of the trajectory of single molecule particles in methyl cellulose hydrogel

Abstract

The development of single molecule spectroscopy and imaging techniques removes the usual ensemble average, allowing the exploration of heterogeneity in many complex

condensed phase environments. These techniques provide information on the statistical distribution of the actual values, such as the probability distribution of an experimental parameter. Such details of the distribution become important when the system under study is heterogeneous. This is expected for materials such as real crystals, polymers or glasses.
