A novel synthesis of new antibacterial nanostructures based on Zn-MOF compound: design, characterization and a high performance application

Abstract

In this study, the novel zinc metal-organic frameworks (MOF) nanostructure has been employed, which was developed using an affordable, environmental friendly, efficient and fast method of ultrasound-assisted reverse micelle (UARM). These nanostructures were identified with various techniques such as FT-IR, XRD, BET, SEM, TG-DSC, TEM and EDS. It was found that the Zn-MOF samples have favorable physicochemical properties. The impact of experimental parameters of the UARM method is effective on the resulting properties, such as high surface area of the products that increases the interactions between the Zn-MOF nanostructure and bacteria.Their antibacterial activities were investigated using diffusion methods in agar and also with dilutions of Zn-MOF samples. Antibiotics (tetracycline and ampicillin) and their anti-biofilm effects were evaluated using microplate method. Obtained results revealed that the Zn-MOF nanostructures have high antibacterial properties which, could be due to the nature of the applied Zn-MOF as well as the optimization process. The Zn-MOF nanostructures could be a novel antibacterial material as biocatalyst processes.

Synthesis of a novel Zn‐MOF/PVA nanofibrous composite as bioorganic material: Design, systematic study and an efficient arsenic removal

“…The method for the preparation of Zn‐MOF has already been reported in our previously published work. [ 48 ]…”

“…Based on the X-pert high score software, the Zn-MOF powder was indexed to the crystalline system confirmed by the previous study. [48] Figure 5 shows that the XRD patterns of the Zn-MOF are well observed in the nanofibrous Zn-MOF/PVA network, but the intensity is quite reduced. By comparing the XRD patterns of Zn-MOF in this study with the sample in previous study, [52] it can be concluded that Zn-MOF crystalline structure remained intact during the course of synthesis of Zn-MOF/PVA nanofibrous samples.…”

“…The method for the preparation of Zn-MOF has already been reported in our previously published work. [48] The FTIR spectrum of the Zn-MOF/PVA polymeric nanofibrous composite was recorded on SHIMADZU FT 8400 Spectrometer and the morphology of the Zn-MOF/ PVA nanofibrous composite was investigated by SEM, Hitachi S-4800. X-ray powder diffraction (XRD) diffractograms were scanned using powder XRD (X' Pert MPD, PAN analytical, Cu Ka) between 10 and 90 (2-Theta) stagewidth of 0.010 00 .…”

Nanomaterials for the Diagnosis and Treatment of Urinary Tract Infections

“…Several nanoparticle-based antimicrobials are used against UTIs such as surfactant-based vesicles, nanoemulsions, and polymeric NPs like chitosan NPs [ 51 , 52 ]. Chitosan NPs have the ability to bind with negatively charged bacterial membranes and to increase their permeability.…”

A comparison of microwave and ultrasound routes to prepare nano-hydroxyapatite fertilizer improving morphological and physiological properties of maize (Zea mays L.)

“…These methods have advantages including high-speed production, low cost and eco-friendliness. In these methods, products with a variety of structures and different physico-chemical properties can be produced [ 37 , 38 ]. To the best of our knowledge, no study has been conducted on the synthesis of Nano-fertilizers using ultrasonic and microwave method.…”
