Spurious Forces on a Brownian Particle in a Diffusion Gradient
Spurious Forces on a Brownian Particle in a Diffusion Gradient
The thermal noise known as Brownian motion acting on microscopic objects (e.g., biomolecules and nanodevices) can be represented as if they were spurious forces. This Demonstration exemplifies these apparent forces acting on a spherical Brownian particle near a wall. You are invited to explore such forces as a function of the particle radius and distance from the wall.
