Development of cellulosic‑based hemostatic dressing with antibacterial activity
Mostafa Goodarz,Amir Behzadnia,Hassan Mohammadi 한국의류학회 2022 Fashion and Textiles Vol.9 No.1
A cotton-based hemostatic dressing featuring antibacterial properties was developed with the potential of being used in trafc accidents to control hemorrhage. Cotton gauze was oxidized initially in an acidic medium and then coated by PVA nanofbers and/or PVA nanofbers loaded with Ciprofoxacin. Fabricated dressings were characterized by FTIR analysis and SEM images. The FTIR spectrum showed the existence of carboxyl groups on the oxidized cotton gauze’s surface. The carboxyl groups content was estimated to be 17.3±0.3 for the oxidized sample with a mixture of nitric acid and phosphoric acid for 24 h (OCF-Mixed acid24). Moreover, the efect of the exposure duration of cotton gauze in the acidic medium on the blood coagulation activity was assessed. It was observed that the OCF-Mixed acid24 sample exhibited an agreeable hemostatic activity (BCIs=10). The antibacterial activity against E. coli and S. aureus bacteria was also captured for the coated cotton gauze by the PVA nanofbers loaded with Ciprofoxacin.
