Folding and unfolding kinetics of DNA hairpins in flowing solution by multiparameter fluorescence correlation spectroscopy
Article Abstract:
Simultaneous two-beam fluorescence cross-correlation spectroscopy and single beam autocorrelation spectroscopy was used to investigate dynamic equilibrium between the folded and unfolded conformations of single stranded DNA hairpin molecules containing polythymine hairpin loops. The analysis revealed nonexponential relaxation kinetics and DNA size-dependent folding times characteristic of dynamic heterogeneity in the DNA hairpin-forming mechanism.

DNA charge transfer: An atomistic model
Article Abstract:
The phenomena of charge transport in DNA using a simple, chemically specific approach are reported, which is intimately related to the Su-Schrieffer-Heeger (SSH) model. The computations provide the corresponding charge-transfer rates in DNA both in the short-range superexchange and in the long-range hopping regime as the output of a single atomistic theory.
