Abstract
A short note on observations of dried patterns of a bi-dispersive colloidal drop on a relatively soft polymer-surface is presented here. The patterns have huge applications in the field of medical diagnosis, fertilization and drug delivery industry and improvement of coating/printing technology. The features in the dried drop involve self-organized open systems. The pattern analysis initiates the predicted mechanism of drying. Drops of liquid containing suspended particles are assumed to be drying on a horizontal semi-solid substrate of a polymer. Study of the fractal geometry of a pattern characterizes the system’s overall behavior and predicts the system’s basic wetting properties.
