Abstract:
An anti-fouling surface having micron scale pillars embedded with Fe3O4 nanoparticles is designed. The pillars may be repeatedly induced to move according to a predetermined frequency, such as one that mimic that of the beating movement of natural cilia, through the application of a magnetic field. When square-shaped pillars with a height of 10 μm, width of 2 μm, and inter-pattern distance of 5 μm actuated for three minutes, more than 99.9 percent of biofilm cells were detached and via gentle rinsing from the surface having the pillars. The anti-fouling surface enables effective prevention of biofilm formation and removal of established biofilms, and can be applied to a broad spectrum of polymers.
