Although clogging is an undesirable random event in many applications, it is the working principle of filtration systems . It is also the reason for their eventual failure. Filters contain a network of pores and channels designed to remove suspended particles while the filtrate flows through . As such, the rate of clogging determines the lifetime of a filter. Clogging has also been employed in disease diagnostics and cell sorting based on the size, shape and deformability of cells in narrow confinements . These applications are made possible by advancements in microfluidic technologies.
