Abstract :
[en] The evaporation of colloids droplets is a naturally abondant phenomenon and is the topic of various and numerous current research. Amongst others, it has been shown that deposits from blood stains depend on the health state from the donor. Understanding the mechanisms leading to the various deposits' structures might then help to understand the composition of the sample. In our work, we studied the influenceinteractions particles, along with the concentration of specific ions the deposit's pattern.
