Robust method of trapping self-propelling particles

The ability to collect self-propelling particles (SPP) is an essential requirement for possible use of SPP in technological applications. In this paper we proposed a novel way of trapping SPP's, through guided trapping of SPP's in V-shaped trap. We performed brownian dynamic simulation via a modified Escape and Predation model developed by L. Angelani (Phys. Rev. Lett., 2012) to assess the validity of the proposed trapping method.
