Conformation dependence of DNA electrophoretic mobility in a converging channel

Conformation dependence of DNA electrophoretic mobility in a converging channel.

The electrophoresis of lambda-DNA is observed in a microscale converging channel where the center-of-masses trajectories of DNA molecules are tracked to measure instantaneous electrophoretic (EP) mobilities of DNA molecules of various stretch lengths and conformations. Contrary to the usual assumption that DNA mobility is a constant, independent of field and DNA length in free solution, we find...

Conformation dependence of DNA exciton parentage.

Singlet electronic excitations of DNA duplex trimers and tetramers with regular homogeneous base-pair sequences ((dA)n.(dT)n and (dG)n.(dC)n, with n=3, 4) have been investigated in vacuo using semiempirical quantum chemistry in a Zerner's Intermediate Neglect of Differential Overlap (ZINDO) approximation. Frequencies, oscillator strengths, and single-electron assignments of many-electron transi...

Numerical study of turbulent forced convection jet flow of nanofluid in a converging sinusoidal channel

Research in convective heat transfer using suspensions of nanometer-sized solid particles in base liquids started only over the past decade. Recent investigations on nanofluid, as such suspensions are often called, indicate that the suspended nanoparticles remarkably change the transport properties and heat transfer characteristics of the suspension. Bending walls can also improve heat transfer...
