How do Graphene Composite Surfaces Affect the Development and Structure of Marine Cyanobacterial Biofilms?

The progress of nanotechnology has prompted the development novel marine antifouling coatings. In this study, influence a pristine graphene nanoplatelet (GNP)-modified surface in cyanobacterial biofilm formation was evaluated over long-term assay using an vitro platform which mimics hydrodynamic conditions that prevail real environments. Surface characterization by Optical Profilometry and Scanning Electron Microscopy shown main difference between GNP incorporated into commercially used epoxy resin (GNP composite) both control surfaces (glass resin) related to roughness topography, where composite had value about 1000 times higher than surfaces. results showed that, after 7 weeks, reduced wet weight (by 44%), thickness 54%), biovolume 82%), coverage 64%) biofilms compared resin. Likewise, GNP-modified delayed development, modulated structure less porous arrangement time, effect at maturation stage. Overall, nanocomposite seems have potential be as material applications. Moreover, multifactorial study crucial understanding interactions properties architecture time.
