Background and Aim: The growing concerns about antibiotic-resistant bacterial strains reveal the urgent need to discover and develop new types of antibacterial agents. Therefore, the aim of the current study is to present a new generation of new antibacterial nanoparticles for industrial medical applications.
Methods: In this experimental study, the biosynthesis process of graphene nanoparticles was performed using an aqueous extract of green algae of Ulva flexuosa. Then the antibacterial activity was evaluated by two methods of determining the diameter of the growth inhibition zone and determining the minimum inhibition concentration on gram-positive and gram-negative bacterial strains.
Results: The results of characterization analyses of graphene oxide reduction with the aqueous extract of the green alga U. flexuosa and its conversion to graphene were confirmed. Evaluation of the antibacterial activity of the samples showed that the aqueous extract of green algae and reduced graphene oxide had antibacterial activity, while graphene oxide had no antibacterial activity.
Conclusion: The results of this study showed that reduced graphene oxide by green macro-algae can be introduced as a new antibacterial to the pharmaceutical field and medicine. |
