A DIFFUSION-BASED APPROACH FOR NANOBEAD DRAG FORCES

摘要：

A central process of the Bead Array Counter (BARC) biosensor involves propelling a dilute solution of streptavidin-coated micron-scale beads through water. It is desirable to downsize these beads, leading to a basic engineering problem: What is the drag force acting on a nanoscale bead having an unknown hydrodynamic boundary condition? We use molecu-lar dynamics simulation to estimate the drag force acting on a hypothetical biosensor nanobead without assuming a no-slip condition or a user-supplied slip parameter.
