“…Anti-pseudomonal drugs such as ciprofloxacin 103ā 105 , meropenem 106 , tobramycin 107, 108 , gentamicin 109 , or amikacin 110 were encapsulated into liposomes or loaded into nanoparticles. The drug delivery systems were diverse in chemical nature and include anionic liposomes 105, 106, 109 , poly(lactic-co-glycolic) acid nanoparticles 110, 111 , water-soluble chitosan oligosaccharide conjugates 112 , oil-in-water cross-linked polymeric nanocomposites 113 , graphen-oxide conjugates 107 , or solid lipid nanoparticles 114 , to name just a few. Alternatively, dry powders 103, 104, 108, 115 or hydrogels 116ā 119 were formulated or wound dressings were coated with a topical antimicrobial such as silver oxynitrate 120 .…”
