Segregation in desiccated sessile drops of biological fluids
Yuri Yu. Tarasevich, Dina M. Pravoslavnova
TL;DR
This paper investigates how the interplay of advection and diffusion during drying causes spatial redistribution of components like albumen and salt in biological fluid drops, explaining observed pattern formations.
Contribution
It reveals the mechanism behind pattern formation in dried biological fluid drops through the interaction of advection and diffusion processes.
Findings
Spatial redistribution of albumen and salt occurs during drying.
Patterns observed in dried biological fluid drops are explained.
Concurrence of advection and diffusion influences component distribution.
Abstract
It is shown here that concurrence between advection and diffusion in a drying sessile drop of a biological fluid can produce spatial redistribution of albumen and salt. The result gives an explanation for the patterns observed in the dried drops of the biological fluids.
