Special Issue Information

Dear Colleagues,

Biofouling and its associated consequences, such as Microbiologically Influenced Corrosion (MIC), are phenomena that are increasingly posing challenges for various societal infrastructures. MIC refers to the detrimental effects that materials can experience due to the presence of microorganisms. Therefore, a key global challenge lies in developing tools to mitigate these issues and combat their adverse impacts on industrial installations. Research in this field has primarily focused on the following subjects:

  • Methodologies for the characterization and early detection of biofouling, such as corrosion analysis through electrochemical or sensor technologies;
  • Monitoring methods for analyzing bacterial corrosion, particularly in the context of nanobiofilm;
  • Innovative nanomaterials with antifouling properties, including antimicrobial, anti-biofilm, and anti-macrofouling characteristics;
  • Emerging green nanotechnologies and approaches for developing protective antifouling coatings;
  • Novel nanomaterials for MIC mitigation, including applied and emergent MIC mitigation nanomaterials;
  • Evaluation methodologies for assessing the antifouling and anti-MIC performance of nanomaterials.

This Special Issue aligns with the objectives of the COST action CA20130–European MIC Network (Euro-MIC; https://www.euro-mic.org/), which provides valuable support in addressing these challenges.

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. Full article

Present worldwide difficulties in healthcare and the environment have motivated the investigation and research of novel materials in an effort to find novel techniques to address the current challenges and requirements. In particular, the use of nanomaterials has demonstrated a significant promise in the fight against bacterial infections and the problem of antibiotic resistance. Metal nanoparticles and carbon-based nanomaterials in particular have been highlighted for their exceptional abilities to inhibit many types of bacteria and pathogens. In order for these materials to be as effective as possible, synthetic techniques are crucial. Therefore, in this review article, we highlight some recent developments in the design and synthesis of various nanomaterials, including metal nanoparticles (e.g., Ag, Zn, or Cu), metal hybrid nanomaterials, and the synthesis of multi-metallic hybrid nanostructured materials. Following that, examples of these materials’ applications in antimicrobial performance targeted at eradicating multi-drug resistant bacteria, material protection such as microbiologically influenced corrosion (MIC), or additives in construction materials have been described.
