Dynamical Scaling Exponents for Polymer Translocation through a Nanopore
Kaifu Luo, Santtu T. T. Ollila, Ilkka Huopaniemi +5
We determine the scaling exponents of polymer translocation (PT) through a nanopore by extensive computer simulations of various microscopic models for chain lengths extending up t…
Comment on ``Passage Times for Unbiased Polymer Translocation through a Narrow Pore''
Kaifu Luo, Tapio Ala-Nissila, See-Chen Ying +2
One of the most fundamental quantities associated with polymer translocation through a nanopore is the translocation time and its dependence on the chain length . Our simula…
Microscopic mechanism for cold denaturation
Cristiano L. Dias, Tapio Ala-Nissila, Mikko Karttunen +2
We elucidate the mechanism of cold denaturation through constant-pressure simulations for a model of hydrophobic molecules in an explicit solvent. We find that the temperature depe…
Reptational dynamics in dissipative particle dynamics simulations of polymer melts
P. Nikunen, I. Vattulainen, M. Karttunen
Understanding the complex viscoelastic properties of polymeric liquids remains a challenge in materials science and soft matter physics. Here, we present a simple and computational…
Dielectrophoresis of nanocolloids: a molecular dynamics study
E. Salonen, E. Terama, I. Vattulainen +1
Dielectrophoresis (DEP), the motion of polarizable particles in non-uniform electric fields, has become an important tool for the transport, separation, and characterization of mic…
Molecular Dynamics Study of Charged Dendrimers in Salt-Free Solution: Effect of Counterions
Andrey A. Gurtovenko, Sergey V. Lyulin, Mikko Karttunen +1
Polyamidoamine (PAMAM) dendrimers, being protonated under physiological conditions, represent a promising class of nonviral, nano-sized vectors for drug and gene delivery. We perfo…
