Simulation of ring-shaped precipitate growth in the single radial immunodiffusion technique. Grid DLA model

The paper offers a mathematical model of ring-shaped precipitate growth in the radial immunodiffusion technique. The model is based on the Witten-Sander grid DLA model. In addition to a set of differential equations "reaction-diffusion", the grid DLA model provides a more vivid and clear physical interpretation of the immunodiffusion precipitate formation process in gel media.
