Vega et al. published a paper in Physics of Fluids. analyzed human tears at the microscopic level to find new ways to modify artificial tears to treat specific dry eye disease symptoms. The in-depth knowledge they gained about the makeup and behavior of tears could be used to study other biological fluids as well as ocular pathogens. The authors used dynamic light scattering to test 10 different artificial tear formulations and collected healthy human tears.
