Investigation of Nano Bacterial Cellulose Coated by Sesamum Oil for Wound Dressing Application

Bacterial cellulose (BC) as a nano fiber hydrogel has many applications in burn treatment and traditionally Sesamum oil was used for this purpose. Accordingly in this research we used purified bacterial cellulose layers which coated by Sesamum oil. The bending property and wettability of specimens were evaluated and the morphology of BC was characterized by AFM and SEM. The obtained result indicated that the amount of bending in coated layer with Sesamum oil is 50% less than untreated wet layer. It is also represent dramatically decrease in layer wettability. In addition the antibacterial property of treated layer has been investigated. All coated layer has shown considerable antibacterial property against gram-positive and -negative bacteria. According to the obtained results, microbial cellulose coated with Sesamum oil has high potential for applying as a modern wound dressing.
