Background: Biofilm-associated infections remain a major challenge in modern medicine due to their high resistance to antibiotics and immune defences. Advances in materials science, chemistry, and nanotechnology have led to the development of innovative, non-antibiotic approaches to prevent or eradicate biofilms. Methods: This review summarises antibiofilm strategies reported between 2020 and 2025, grouped into chemical, enzymatic, physical–photonic, nanomaterial-based, and biological hybrid categories. Results: Chemical methods such as silver-based chemical systems, nitric oxide donors, and biosurfactants disrupt bacterial membranes, generate reactive oxygen species, and inhibit quorum sensing. Enzymatic coatings with DNase I or lysostaphin effectively reduce Staphylococcus aureus and S. epidermidis biofilms, showing stability after sterilisation and high biocompatibility. Physical–photonic techniques, including photocatalytic and light-activated coatings, provide controllable and renewable antibacterial activity. Nanomaterials such as silver nanomaterials, chitosan-based carriers, magnetic ferrites, and catalytic nanozymes enable targeted, ROS-mediated biofilm disruption. Biologically derived systems, including bacteriophage hydrogels and plant metabolites, offer eco-friendly, biocompatible alternatives. Conclusions: Recent antibiofilm innovations mark a transition from conventional antibiotics to multifunctional and adaptive systems integrating chemical, enzymatic, and physical mechanisms for effective biofilm control on medical surfaces.
