Investigating Citrobacter sp. MICI21 Biofilm Growth on Patterned 2D Graphene, hBN, and Diamond Surfaces

Biofouling, the accumulation of microorganisms, plants, and algae on wet surfaces, poses significant challenges to the freshwater and marine industries. In pursuit of eco-friendly mitigation strategies, we investigate the attachment and biofilm growth of Citrobacter sp. MICI21 on patterned 2D surfaces. The study focused on 2D surfaces composed of Graphene, hexagonal Boron Nitride (hBN), and/or Diamond on an underlying Copper substrate. The study aims to determine the degree of preferential growth on these different 2D patterned materials and to understand how it changes the effective surface chemistry of the substrate.
