In this paper, we describe theoretically a most remarkable situation where end-charged polyelectrolyte brushes significantly enhance the diffusioosmotic transport in nanochannels by localizing the electric double layer charge density away from the channel walls…this is Raja’s first paper, Harnoor’s 6th, and Haoyuan 8th paper from the group. A BIG congratulations to all of them !!!!!

Prof. Das delivers an invited talk titled “Modeling Transport in Microfluidic Systems: Towards Better Equipping Ourselves for Solving Biomedical Engineering Problems” at US Food and Drug Administration

In our 2015 Nature Communication paper, we have provided a force-based argument  to explain the drop motion. A recent paper in PNAS claimed our theory to be flawed on the basis of an energy-dissipation-based argument. In this paper, which is a Letter to the Editor, we showed that the claim of this PNAS paper was

In this paper, we propose a new design where biomimetic nanoparticles (NPs) use electrostatic interactions to simultaneously promote specific adhesion and prevent non-specific adhesion to plasma membranes.

In this paper, we study the force-driven translocation of a water nanodrop through a holey graphene matrix demonstrating a capillarity-mediated breakdown of Darcy’s Law.

In this paper, we show that in nanochannels functionalized with end-charged polyelectrolyte brushes one can significantly augment the efficiency of the electrokinetic energy conversion.

The thesis topic was “BILAYER MEMBRANE ELECTROSTATICS AND CHARGE-REGULATED MEMBRANE NANOPARTICLE INTERACTIONS”. Shayandev is 2nd PhD to graduate from SMIEL…many congratulations Shayandev

The topic of the thesis was “ENHANCED DIFFUSIOOSMOSIS AND THERMOOSMOSIS IN POLYELECTROLYTE-BRUSH-FUNCTIONALIZED NANOCHANNELS”. This is the second MS from SMIEL…Many congratulations Raja….

Prof. Siddhartha Das delivered an invited talk titled “Water and Ions at Nanoscopic Interfaces: From 2-D materials to plasma membranes” at the Waterloo Institute of Nanotechnology (WIN) of the University of Waterloo.
