Ionic Cloud Distribution close to a Charged Surface in the Presence of Salt
Olli Punkkinen, Ali Naji, Rudolf Podgornik +2
Despite its importance, the understanding of ionic cloud distribution close to a charged macroion under physiological salt conditions has remained very limited especially for stron…
Enhanced dielectrophoresis of nanocolloids by dimer formation
Emppu Salonen, Emma Terama, Ilpo Vattulainen +1
We investigate the dielectrophoretic motion of charge-neutral, polarizable nanocolloids through molecular dynamics simulations. Comparison to analytical results derived for continu…
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…
