Microscale patterned surfaces reduce bacterial fouling-microscopic and theoretical analysis

- Study on effect of patterned surfaces on Eneterobacter cloacae fouling, responsible for HAIs.
- Results show significantly reduced E. Cloace fouling on patterned surfaces vs the smooth control.
- Mechanism1: Patterned surfaces have increased recessed region attachment surface area.
- Mechanism2: Partially wetted Cassie state, present in certain classes of patterned surfaces.
- Fouling reduction may be due to these mechanisms, perhaps aided by quorum sensing.
