“…Marine biofilm formation is a nanoscale interfacial phenomenon. As such, innovative surface engineering techniques that modify surface attributes at the nanoscale can not only optimize the properties of certain materials [ 24 , 25 ], but also provide them with significant antifouling potential [ 26 , 27 ]. In fact, the incorporation of nanomaterials into marine antifouling paints has been reported to greatly impact a surface’s charge potential, hydrophobicity, and topography, as well as its antibacterial and anticorrosion properties [ 28 , 29 ].…”

Due to its several economic and ecological consequences, biofouling is a widely recognized concern in the marine sector. The search for non-biocide-release antifouling coatings has been on the rise, with carbon-nanocoated surfaces showing promising activity. This work aimed to study the impact of pristine graphene nanoplatelets (GNP) on biofilm development through the representative marine bacteria Cobetia marina and to investigate the antibacterial mechanisms of action of this material. For this purpose, a flow cytometric analysis was performed and a GNP/polydimethylsiloxane (PDMS) surface containing 5 wt% GNP (G5/PDMS) was produced, characterized, and assessed regarding its biofilm mitigation potential over 42 days in controlled hydrodynamic conditions that mimic marine environments. Flow cytometry revealed membrane damage, greater metabolic activity, and endogenous reactive oxygen species (ROS) production by C. marina when exposed to GNP 5% (w/v) for 24 h. In addition, C. marina biofilms formed on G5/PDMS showed consistently lower cell count and thickness (up to 43% reductions) than PDMS. Biofilm architecture analysis indicated that mature biofilms developed on the graphene-based surface had fewer empty spaces (34% reduction) and reduced biovolume (25% reduction) compared to PDMS. Overall, the GNP-based surface inhibited C. marina biofilm development, showing promising potential as a marine antifouling coating.

Biofouling is a serious concern and can cause health risks and financial burdens in many settings such as maritime structures, medical devices, and water treatment plants. Many technologies employing toxic biocides, antifouling toxic coatings, and chlorine have been established to prevent or impede biofouling. However, their applications are limited due to environmental and health concerns regarding biocides and coating materials. To overcome this, novel antifouling coatings employing ecofriendly, nontoxic nanomaterials and appreciable antimicrobial and antibiofilm properties have been developed. Due to intrinsic antimicrobial properties, these antifouling nanocoatings have been proven to be effective against several water-borne microorganisms. Various nanostructures of metals (silver, copper, and gold), metal oxides (zinc oxide, titanium oxide, copper oxide, and cerium oxide), carbon (graphene and carbon nanotubes), and metal nanocomposites inhibit the biocorrosion and biofilm formation caused by bacteria. Besides, antifouling technology developed based on nanocontainers releases key active substances that promote selfcleaning, anticorrosion, and antibiofilm properties. This review provides a comprehensive overview of nanotechnology-enabled antifouling agents developed to combat micro-and macrofouling phenomena. Moreover, the recent progress in the applications of antifouling coatings in industrial sectors such as marine (ships), water-treatment plants, and medical devices is elaborated with relevant examples. The mechanistic insights into the inhibitory action of bacterial cell growth and biofilm formation by antifouling nanocoatings are presented. The challenges associated with developing antifouling nanoproducts, their practical limitations, and prospects are also discussed.

Although carbon materials are widely used in surface engineering, particularly graphene (GP) and carbon nanotubes (CNTs), the application of these nanocomposites for the development of antibiofilm marine surfaces is still poorly documented. The aim of this study was, thus, to gather and discuss the relevant literature concerning the antifouling performance of carbon-based coatings against marine micro- and macrofoulers. For this purpose, a PRISMA-oriented systematic review was conducted based on predefined criteria, which resulted in the selection of thirty studies for a qualitative synthesis. In addition, the retrieved publications were subjected to a quality assessment process based on an adapted Methodological Index for Non-Randomized Studies (MINORS) scale. In general, this review demonstrated the promising antifouling performance of these carbon nanomaterials in marine environments. Further, results from the revised studies suggested that functionalized GP- and CNTs-based marine coatings exhibited improved antifouling performance compared to these materials in pristine forms. Thanks to their high self-cleaning and enhanced antimicrobial properties, as well as durability, these functionalized composites showed outstanding results in protecting submerged surfaces from the settlement of fouling organisms in marine settings. Overall, these findings can pave the way for the development of new carbon-engineered surfaces capable of preventing marine biofouling.
