“…ROS production has been found for various metal compounds, and these nanoparticles can lead to oxidative stress, inflammation, and consequent damage to proteins, cell membranes, and DNA, which is one of the main mechanisms of nanotoxicity [ 47 ]. The results of plate-coating experiments ( Figure 14 ) revealed that bacteria treated with MIL-101(Fe)@Ag (Ag 0.0127 wt%) produced more ROS than those treated with MIL-101(Fe), and few ROS were produced by bacteria not treated with MIL-101(Fe)@Ag (Ag 0.0127 wt%), indicating that the bacterial cell membranes treated with MIL-101(Fe)@Ag were disrupted and produced more ROS [ 32 , 59 , 60 ].…”

Metal-organic frameworks (MOFs), which have become popular in recent years as excellent carriers of drugs and biomimetic materials, have provided new research ideas for fighting pathogenic bacterial infections. Although various antimicrobial metal ions can be added to MOFs with physical methods, such as impregnation, to inhibit bacterial multiplication, this is inefficient and has many problems, such as an uneven distribution of antimicrobial ions in the MOF and the need for the simultaneous addition of large doses of metal ions. Here, we report on the use of MIL-101(Fe)@Ag with efficient metal-ion release and strong antimicrobial efficiency for co-sterilization. Fe-based MIL-101(Fe) was synthesized, and then Ag+ was uniformly introduced into the MOF by the substitution of Ag+ for Fe3+. Scanning electron microscopy, powder X-ray diffraction (PXRD) Fourier transform infrared spectroscopy, and thermogravimetric analysis were used to investigate the synthesized MIL-101(Fe)@Ag. The characteristic peaks of MIL-101(Fe) and silver ions could be clearly seen in the PXRD pattern. Comparing the diffraction peaks of the simulated PXRD patterns clearly showed that MIL-101(Fe) was successfully constructed and silver ions were successfully loaded into MIL-101(Fe) to synthesize an MOF with a bimetallic structure, that is, the target product MIL-101(Fe)@Ag. The antibacterial mechanism of the MOF material was also investigated. MIL-101(Fe)@Ag exhibited low cytotoxicity, so it has potential applications in the biological field. Overall, MIL-101(Fe)@Ag is an easily fabricated structurally engineered nanocomposite with broad-spectrum bactericidal activity.

“…Numerous biological reports have been reported from organic metal frameworks, including inhibition of human glioma cell growth [ 12 ], anticancer activity [ 13 – 15 ], and antimicrobial properties [ 16 – 18 ]. One of the MOFs with high biological properties is Cu-MOF [ 19 – 21 ]. It is worth noting that the true nature of the active sites in many MOFs containing metal ions is saturated with the coordination of organic ligands [ 22 ].…”

The ultrasonic assisted reverse micelle method (UARM) was used to synthesize Cu-MOF from Cu(NO3)2·3H2O and 2,6-pyridine dicarboxylic acid in a 1:1 molar proportion. It has been characterized using FT-IR, XRD, nitrogen adsorption analysis, SEM and TEM–EDX. The morphology of Cu-MOFs was spherical, with an average particle size distribution of less than 100 nm. Using BET analysis, the surface area of Cu-MOF was found to be 284.94 m2/g. The porous morphology of Cu-MOF was also suggested by SEM and TEM analyses. It has anticancer properties against MCF-7 breast cancer cells. Cytotoxicity testing was performed on MCF-7 breast cancer cells using the MTT cell viability assay, and cell proliferation and viability were found to be approximately 24% higher than the control.

“…Among these, voltammetry is the proposed method for bypassing such problems due to its unique advantages such as rapid response, inherent selectivity, great sensitivity, simplicity, cost-effectiveness, and relatively short analysis time to determine organic molecules such as drugs and relevant molecules in biological fluids and pharmaceutical doses (Maaref et al, 2018;József et al, 2019;Salajegheh et al, 2019; Sargazi et al, 2019;Shetti et al, 2019;Kulkarni et al, 2020;Malode et al, 2020;Vakili Fathabadi et al, 2020;Liu et al, 2021a;Foroughi et al, 2021;Obireddy and Lai, 2021;Obireddy and Lai, 2022). An effective strategy to increase the electrochemical performance of sensors is to design composites by integrating highly electrocatalytic active materials with excellent conductivity materials, resulting in the electrode surface modification (Zhang et al, 2016;Foroughi and Ranjbar, 2017;Shetti et al, 2018;Fathi et al, 2020;Azizabadi et al, 2021;Liu et al, 2021b;Liang et al, 2022;Qi et al, 2022).…”

This study synthesized a La2O3@snowflake-like Cu2S composite to fabricate an electrochemical sensor for sensitively simultaneous detection of diclofenac and chlorzoxazone exploiting an easy hydrothermal approach, followed by analysis with XRD, FE-SEM, and EDX methods. According to voltammetric studies, the electrocatalytic diclofenac and chlorzoxazone oxidations on the electrode modified with La2O3@SF-L Cu2S composites were increased, with greater oxidation currents, as well as the oxidation potential was significantly decreased due to synergetic impact of La2O3@SF-L Cu2S composites when compared with the pure SF-L Cu2S NS-modified electrode. The differential pulse voltammetry findings showed wide straight lines (0.01–900.0 μM) for La2O3 NP@SF-L Cu2S NS-modified electrode with a limit of detection (LOD) of 1.7 and 2.3 nM for the detection of diclofenac and chlorzoxazone, respectively. In addition, the limit of quantification was calculated to be 5.7 and 7.6 nM for diclofenac and chlorzoxazone, respectively. The diffusion coefficient was calculated to be 1.16 × 10−5and 8.4 × 10−6 cm2/s for diclofenac and chlorzoxazone oxidation on the modified electrode, respectively. Our proposed electrode was examined for applicability by detecting diclofenac and chlorzoxazone in real specimens.
