Real-Time Force Measurement Between Emulsion Droplets During Enzymatic Breakdown

This protocol introduces a unique methodology for investigating the stability of emulsions and the dynamic disintegration of emulsion droplets during enzymatic digestion using dual-trap optical tweezers. The process involves preparing the emulsion, introducing the enzyme, and configuring a force measurement system to monitor inter-droplet forces in real time. By employing dual-trap optical tweezers, the method enables precise manipulation and observation of emulsion droplets, facilitating the measurement of forces between droplets during enzymatic disintegration. This experimental technique offers significant insights into the interactions and stability of emulsions during digestion, with particular relevance to research in food science, pharmaceuticals, and other industries involving organic emulsions. The method is adaptable and applicable to various optical tweezer setups and different types of emulsions or enzymes, serving as a versatile tool for exploring mechanical properties and disintegration processes across a range of fields. Furthermore, this visual approach provides the advantage of real-time monitoring of force dynamics, opening new avenues for studying emulsion behavior in diverse applications.
