Stability of the Co-Swimming Condition in Non-Spherical Active Droplet Systems

Micro-swimmers are playing an increasingly critical role in biomedical applications such as drug delivery. Our previous work in this realm considered a model micro-swimmer encapsulated in a viscous droplet. We identified conditions necessary for the micro-swimmer and the droplet to move at the same speed, namely, co-swimming. Building on our previous work, we will present a time-dependent, numerical analysis of the stability of the co-swimming state for a range of swimmer and droplet's geometries, as well as biologically relevant fluid environments.
