hydrophobic patch would move faster than the ones with an hydrophilic patch.]{} [Similarly, Gao et al [@Gao_OTSJanusExp], studied self-assembly of amphiphilic particles made with hydrophobic octadecyltrichlorosilane (OTS)-modified silica microspheres capped with a catalytic Pt hemisphere patch.]{} [Additionally, Yan et al [@Dipolar_Granick] have recently reported different collective states of active dipolar Janus colloids, whose motion is originated by an induced-charge electrophoresis. These colloids self-assemble in different morphologies, ranging from: gas, swarms, chains and clusters, by modifying both the charge imbalance of the colloids and the electric field frequency. Moreover, in [@Dipolar_Granick], the authors were able to numerically reproduce all observed states by means of an overdamped molecular dynamics simulation whose particles were interacting via directed imbalanced interactions.]{}

[Motivated by these two experimental works [@Gao_OTSJanusExp; @Dipolar_Granick], simulations of a dilute quasi-2D suspension of ABP interacting via anisotropic amphiphilic Janus interactions have been reported in Ref. [@Stewart_17]. To the best of our knowledge, this is the first numerical attempt to unravel the collective behaviour of amphiphilic active Janus particles, taking into account their anisotropic nature. In Ref. [@Stewart_17] both the effect of interaction directionality and the propulsion speed have been used to control the physical properties of the assembled active aggregates. One might
