  We study the irreversible adsorption of patchy particles on substrates in the
limit of advective mass transport. Recent numerical results show that the
interface roughening depends strongly on the particle attributes, such as,
patch-patch correlations, bond flexibility, and strength of the interactions,
uncovering new absorbing phase transitions. Here, we revisit these results and
discuss in detail the transitions. In particular, we present new evidence that
the tricritical point, observed in systems of particles with flexible patches,
is in the tricritical directed percolation universality class. A scaling
analysis of the time evolution of the correlation length for the aggregation of
patchy particles with distinct bonding energies confirms that the critical
regime is in the Kardar-Parisi-Zhang with quenched disorder universality class.
