The emergence of antibiotic resistant <em>P. aeruginosa </em>infections has created significant challenges in treating these patients. A potential alternative treatment for antibiotic resistant pathogens includes the use of carbon nanotubes (CNTs), which have received considerable attention due to their potent antibacterial activity. The aim of this study was to construct a novel CNT containing an anti-bacterial chemical component to effectively combat drug resistant <em>P. aeruginosa </em>infections.<br> <br> <strong><em>Methods:</em></strong> In this study, a novel chemical component was synthesized and coated the CNT. The antimicrobial effects were then evaluated on MDR, XDR, and PDR strains of <em>P. aeruginosa </em>isolated from burn patients. Antibiotic susceptibility was evaluated using the disk diffusion test and minimum inhibitory concentration (MIC) testing. In order to determine the potential cytotoxicity, an MTT assay was performed on Human Dermal Fibroblasts. The effect of treatment on the expression of wound healing genes was analyzed via qRT-PCR.<br> <br> <strong><em>Results</em></strong><strong><em>:</em></strong> Experimental data indicates that our CNT coated chemical compound had antibacterial properties, negligible cytotoxicity, and could accelerate the wound healing process.<br> <br> <strong><em>Conclusions:</em></strong> Given the antibacterial properties of our CNT chemical compound, it has the potential to treat and reduce the occurrence of multi-drug resistant <em>P. aeruginosa </em>burn wound infections and aid in wound healing by turning on genes (VEGFA, EGF and PDEGF) involved in the wound healing process.</div> Anti-Bacterial drugs, Drug resistance, Nanotubes Carbon, Pseudomonas aeruginosa, MDR, XDR. 89 96 http://rbmb.net/browse.php?a_code=A-10-437-1&slc_lang=en&sid=1 Kamelia Banihashemi camelliaba@yahoo.com 100319475328460017539 100319475328460017539 No Department of Biology, Science and Research branch, Islamic Azad University, Tehran, Iran.
