| Abstract Scope |
Active particles refer to systems capable of consuming chemical energy from the environment and converting it to mechanical energy. Current literature explains how confinement affects passive particles due to steric and hydrodynamic hindrance. However, that is not the case for autonomous active particles. This work seeks to explore how and why geometric constraints affect the reaction rate of active particles, leading to a change in their diffusivities. To study the “how”, we carried out motion and kinetic studies within chambers of different sizes, altering the confinement of the active particles. To study the “why”, numerical simulations gave insights into the mechanisms that allow this phenomenon to occur. We expect the results from this work to provide a broader understanding of how autonomous active particles are affected when they are subjected to confined spaces and shed light into the mechanisms that govern catalysis, sensing and transport in microscale confined geometries. |
