Since their discovery by Bangham and coworkers almost four decades ago, liposomes have become models for biomembranes and vehicles for pharmaceutical, diagnostic, and cosmetic agents. One of the advantages of using liposomes as a drug vehicle is their ability for slow release, thus reducing dosage, localizing a drug, and minimizing its side-effects. Antibiotic resistance is a growing global problem, including for ocular bacterial infection by Staphylococcus aureus, where time is an important parameter that determines the severity of infection. This situation has prompted the pursuit of ways to prepare drug-encapsulating liposomes that enable bulk release of the drug chloramphenicol (CAP) onc..
