Abstract

Nanomaterials are increasingly used to the targeting of gram-positive and gram-negative bacteria as an alternative to antibiotics. Bacterial infections are a major cause of chronic infections and mortality. People requirement for new materials for pathogenic bacteria treatment. It seems that nanomaterial-based strategies can be resolving this problem. In this research, improved antibacterial nanofibrous material using the synthesis of novel blend nanofibers by electrospinning method against gram-positive and gram-negative bacteria. First, Honey as a natural, biocompatible and antimicrobial compound (with different percentages) was added to the PDDA solution and the influence of processing parameters on the morphology of the electrospun blend nanofibers were investigated. The results showed that a bead-free morphology of nanofibers with uniform diameter achieved at the concentration ratio of 40/60% (PDDA/honey), the flow rate of 0.8 mL/h and the high voltage of 17kV. The sample with optimum morphology was cross-linked by glutaraldehyde at different crosslinking times. Evaluation of the water absorption property of nanofibers showed the absorption capacity of 4.9 g/g. Then, the in-vitro antibacterial activity of nanofiber investigated against gram-positive and gram-negative strains, Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli). Afterward, novel nanofiber antibacterial activity studied against pathogenic Pseudomonas aeruginosa (P. aeruginosa). The MIC values indicated that the ratio of 40/60% PDDA/honey nanofiber induced about 99.9% bacterial death for both strains. Moreover, the novel PDDA/honey nanofibers showed suitable antibacterial activity (98.89 %) against pathogenic Pseudomonas aeruginosa. Moreover, the results showed a large reduction of bacterial numbers and evidently presented novel nanofibers as new antimicrobial agents...
