“…Among others, lamellar and non-lamellar liquid crystalline phases, particularly inverse bicontinuous cubic (Q 2 ) and hexagonal (H 2 ) phases, may find application in next-generation antibacterial coatings, as depicted in Figure 3 . This is attributed to their unique nanostructural versatility, the biocompatibility of their major lipid constituents (such as monounsaturated monoglycerides, diunsaturated monoglycerides, and omega-3 fatty acid monoglycerides), bioadhesive properties, and capability of loading and sustaining the release of amphiphilic, hydrophobic, and hydrophilic drugs [ 112 , 113 , 114 , 115 , 116 , 117 , 118 , 119 , 120 , 121 , 122 , 123 ]. Further, it is worth exploring the possible functionalization of hydrogels or polymeric matrices by embedding the corresponding nanoparticles of the inverse non-lamellar lyotropic liquid crystalline phases (particularly cubosomes and hexosomes), which are recently popular nano-self-assemblies in the development of nanocarriers for drug delivery applications [ 124 , 125 , 126 , 127 , 128 , 129 , 130 , 131 , 132 , 133 , 134 , 135 , 136 , 137 , 138 , 139 , 140 , 141 , 142 ], or through their immobilization for designing cubosome or hexosome coatings by employing chemical surface activation methods.…”

Implant-associated infections (IAIs) represent a major health burden due to the complex structural features of biofilms and their inherent tolerance to antimicrobial agents and the immune system. Thus, the viable options to eradicate biofilms embedded on medical implants are surgical operations and long-term and repeated antibiotic courses. Recent years have witnessed a growing interest in the development of robust and reliable strategies for prevention and treatment of IAIs. In particular, it seems promising to develop materials with anti-biofouling and antibacterial properties for combating IAIs on implants. In this contribution, we exclusively focus on recent advances in the development of modified and functionalized implant surfaces for inhibiting bacterial attachment and eventually biofilm formation on orthopedic implants. Further, we highlight recent progress in the development of antibacterial coatings (including self-assembled nanocoatings) for preventing biofilm formation on orthopedic implants. Among the recently introduced approaches for development of efficient and durable antibacterial coatings, we focus on the use of safe and biocompatible materials with excellent antibacterial activities for local delivery of combinatorial antimicrobial agents for preventing and treating IAIs and overcoming antimicrobial resistance.
