Recently, methods based on droplet evaporation find application in various fields of science and technology, as for instance in medical diagnosis. It is based on the idea that in the case of some disease’s patterns formed in desiccated droplets of some specific corporal fluids (e.g. blood, serum, tears, sweat) would differ depending on whether the fluid was taken from a diseased or healthy donor, since the disease would specifically modify the composition of the fluid.
