Sonochemical-assisted method for efficient synthesis of Cu-MOF and evaluating its antibacterial properties

Abstract

Sonochemical-assisted method was used to synthesize copper metal-organic frameworks (Cu-MOF) nanostructures. The final products were examined by related techniques such as XRD patterns, SEM image, BET N2 adsorption/desorption technique and FTIR spectrum. Microtiter plates microbiological assay were used to investigate antibacterial properties and the results were analyzed using ANOVA and Tukey HSD tests. The results showed that Cu-MOF nanostructures have a mesoporous nature with an average particle size distribution around 60 nm. The final product had the property of preventing the growth of all tested bacteria in certain concentrations. Minimum Inhibitory Concentration (MIC) values were observed in the range of 30–100 ppm. It was also discovered that this nanostructure can not kill bacteria completely. In addition, the minimal inhibitory concentration for biofilm growth (MIC-B) of the nanostructure was investigated. The MIC-B analyzes demonstrated that the growth of bacterial biofilm decreased with increasing Cu-MOF concentration.
