Modeling Spatial Correlation of DNA Deformation: DNA Allostery in Protein Binding
Published 2014“…This length scale is in agreement with that reported from the single-molecule experiment. Our model can be reduced to the worm-like chain form at length scales larger than lP but is able to explain DNA’s mechanical properties on shorter length scales, in particular, the DNA allostery of protein–DNA interactions.…”

Single-molecule chemistry studied using the protein pore -α-hemolysin
Published 2012“…However, due to the ‘slow’ reaction rate of the Diels-Alder reaction (rate constant ~10⁻¹ M⁻¹s⁻) relative to the time-scale of the single-molecule experiment, we failed to observed chemical conversion at the single-molecule level. …”
