Phoretic interactions of two chemically-active particles — •Babak Nasouri1 and Ramin Golestanian1,2 — 1Max Planck Institute for Dynamics and Self-Organization (MPIDS), 37077 Goettingen, Germany — 2Rudolf Peierls Centre for Theoretical Physics, University of Oxford, Oxford OX1 3PU, United Kingdom
Catalytically-coated active particles in a viscous medium interact with one another by altering the chemical and hydrodynamic fields in their surroundings. Such phoretic interactions may drive particles in motion and are strongly dependent on the physico-chemical properties of the system, namely: the response of the particles to the interaction fields, and geometric factors such as inter-particle distances and particle sizes. In this work, we discuss an analytical approach which can accurately capture the dynamical behaviour of two phoretic spherical particles, for any given configuration.
