Understanding and characterizing soft systems—ubiquitous in materials science and biophysics—requires precise knowledge of their rheological and interfacial properties, such as viscosity and sur-face tension. These properties are not always uniform: many dynamic processes, like the solute or thermal Marangoni effect and surfactant-driven interfacial motion, are governed by spatial variations in these same interfacial parameters. Yet, capturing these interfacial variations remains a significant experimental challenge—especially at the micrometric scale, where traditional methods fall short, and in out-of-equilibrium systems, where many fundamental questions are still unresolved. This project aims to tackle this challenge by developing an innovative, non-invasive optical technique capable of simultaneously measuring interfacial properties in real time and across multiple points of a micrometric interface. The final goal of the PhD project is to achieve the first-ever 2D mapping of interfacial properties in non-equilibrium systems—a breakthrough that could revolutionize how we understand and control interfacial dynamics at small scales.
