Fig. 5: (A) Glass slides half-coated with lubricant-infused PDMS were incubated in culture vessels containing B. braunii. After 12 days, the slides were slowly removed from the vessel using a dip coater attached to the slide. At t=0 and t=5 seconds, the clear attachment of the algae biofilm to the untreated glass can be seen. However, at t=15 the boundary between the treated and untreated class is crossed, and at t=16 the biofilm begins to peel away from the surface. The arrow at t=35 indicates the intact biofilm floating on the surface of the culture medium. (B) Percent biofilm surface coverage of the glass substrates, untreated PDMS substrates, and lubricant-infused PDMS substrates after removal. (C) Amount of chlorophyll a remaining on the surfaces after removal.
