DNA molecular solvation in neat ionic liquids.
The structural and molecular mechanism of double-stranded DNA (dsDNA) and single-stranded DNA (ssDNA) solvation in ten room-temperature ionic liquids (RTILs) is disclosed herein. We show that the Drew Dickerson B DNA structure solvated in neat RTILs based on imidazolium, oxazolium, pyrrolidinium, pyrimidinium and quaternary ammonium cations, combined with hexafluorophosphate and tetrafluorobrom...
متن کاملDouble layer in ionic liquids: overscreening versus crowding.
We develop a simple Landau-Ginzburg-type continuum theory of solvent-free ionic liquids and use it to predict the structure of the electrical double layer. The model captures overscreening from short-range correlations, dominant at small voltages, and steric constraints of finite ion sizes, which prevail at large voltages. Increasing the voltage gradually suppresses overscreening in favor of th...
متن کاملSUPPLEMENTARY INFORMATION Double layer in ionic liquids: Overscreening vs. crowding
where ε̂ is a linear operator, whose Fourier transform ε̂(k) encodes how the permittivity depends on the wavelength 2π/k of the k-Fourier component of the field, due to discrete ion-ion correlations, as well as any non-local dielectric response of the ions, such as exponentially decaying Debye correlations in ionic plasma, as well as correlations in polarization flucutations due to any other mole...

متن کاملPackaging double-helical DNA into viral capsids.
DNA packaging in bacteriophage P4 has been examined using a molecular mechanics model with a reduced representation containing one pseudoatom per turn of the double helix. The model is a discretized version of an elastic continuum model. The DNA is inserted piecewise into the model capsid, with the structure being reoptimized after each piece is inserted. Various optimization protocols were inv...
