Bacterial adhesion and biofilm formation present significant operational and health risks across healthcare, food packaging and storage, and the marine sector. To combat these issues, ongoing research focuses on the design and fabrication of specialised antibacterial surfaces. These materials are engineered to repel bacterial attachment, eradicate bacteria that succeed in adhering, and prevent or disrupt the establishment of biofilms. Recent approaches encompass various manufacturing methods, analytical surface characterisation tools, and a detailed examination of the biological mechanisms behind microbial adhesion. Reviewing the practical benefits and operational drawbacks of existing fabrication techniques provides critical guidance for future surface designs tailored to industrial requirements.
Biofilms are notoriously difficult to eradicate and can lead to persistent infections, spoiled food products, and damaged marine equipment. Understanding how surfaces can be designed to resist bacterial attachment or kill microbes on contact offers a path towards cleaner environments and reduced reliance on post-contamination treatments across essential public health and industrial settings.
Potential applications exist for manufacturers and operators in healthcare, food storage and packaging, and marine engineering seeking to limit biological fouling. Because the abstract outlines a broad review of fabrication strategies, characterisation tools, and mechanisms rather than a single tested product, the work sits at an early, foundational stage of development without immediate near-market deployment data.

Adhesion of bacteria on surfaces and the resultant biofilm formation is a great risk to human health care services, food packaging and storage, and the marine industry. This has necessitated the need for the scientific community and industries to continually develop ways of fabricating surfaces that can prevent bacterial adhesion, kill adhered bacteria, and prevent/disrupt biofilm formation. Therefore, this review is focused on providing an up-to-date discussion on the recent strategies adopted by researchers in the design of antibacterial surfaces. It highlighted the different surface characterization techniques, discussed the mechanism of bacteria adhesion and biofilm formation, reviewed the recent method of fabricating antibacterial surfaces and their industrial applications, emphasized the advantages and drawbacks of these techniques, and proposed outlooks for future designs.
