Furthermore, we find that the dynamics of these chains is also affected by the number and location of active units. We report this using the mean first passage time required to reach location of highest activity, which decreases with increasing number of active units. 10/n

We report that different locations and number of active units in the chain lead to different accumulation behaviour. Surprisingly, chains with fewer active units do better than chains uniquely composed of ABPs. 9/n

Moreover, with a large enough chiral torque composites with small passive counterpart can also accumulate in high activity. This goes further than previous studies (PRL 126, 208102) where accumulation in high activity was possible only beyond a certain size of the passive part of the composite. 5/n

Starting with stochastic differential equations followed by coarse graining, we find that the accumulation behaviour can be tuned using the chiral torque. This gives another handle on controlling the accumulation of ABPs, complementing new experimental setups with magnetotactic swimmers. 4/n
