spreading and diagnostics. Other than the obvious biological influences on such
motion, it can be imagined that the network topology plays a role in how far a swim-
mer can traverse through such networks. Such a situation can be mimicked by cre-
ating a complex enough, yet quantifiable, network of microfluidic channels through
which the droplet squirmers can traverse as shown in Fig.
7.19
. As we discussed
in this chapter, the complex interplay of the effects of confinement, hydrodynamic
interactions and network topology could lead to truly interesting behaviour.
