“…[34] On the other hand, possible synergistic gradual degradation of Tri-MOF and release of metal ions from the pristine Tri-MOF metal cluster showed enhanced bacterial inactivation efficiency with 90.9 AE 4.4% at a concentration of 2.27 mg mL À1 . [61] Interestingly, the LIG/Tri-MOF composite showed enhanced antibacterial activity compared to Tri-MOF, with ≈20% enhanced bacterial removal for Gram-negative bacteria. LIG/Tri-MOF composite at a concentration of 1.14 mg mL À1 resulted in ≥90% bacterial inhibition, which might be a synergistic effect of the presence of LIG, which is known to agglomerate the bacteria, and a close association of the bacteria with the Tri-MOF combined with the gradual degradation of Tri-MOF clusters could enhance the activity.…”

“…As such, if the LIG can engulf and aggregate bacterial cells in close proximity to the leaching toxic metal ions, an enhanced activity might occur (Figure 6d,f ). [61] In summary, Figure 6g illustrates the antibacterial action of the LIG/Tri-MOF composite. Overall, the findings presented in this work showed the potential concept of a LIG/antibacterial composite as an effective material against bacterial proliferation.…”

“…LIG/Tri-MOF composite at a concentration of 1.14 mg mL À1 resulted in ≥90% bacterial inhibition, which might be a synergistic effect of the presence of LIG, which is known to agglomerate the bacteria, and a close association of the bacteria with the Tri-MOF combined with the gradual degradation of Tri-MOF clusters could enhance the activity. [38,61] Less bacterial growth inhibition was seen when LIG powder and Tri-MOF that were manufactured separately were mechanically combined in comparison to the LIG/Tri-MOF composite, which may be attributed to the existence of more aggregated bacterial culture on the LIG surface than in the suspension.…”

Crystalline and porous metal‐organic frameworks (MOFs) are potential candidates for different antibacterial, photocatalytic, and adsorption applications. Moreover, multi‐principal element nanoparticles are effective against multidrug‐resistant bacteria, and combining metals with carbon nanomaterials can enhance activity. In this study, a Tri‐MOF comprised of iron, zinc, and cobalt and 2‐methyl imidazole was grown together with laser‐induced graphene (LIG) powder. Electron microscopy imaging showed the successful preparation and the crystalline nature of the LIG/Tri‐MOF composite. Fourier‐transform infrared and X‐ray photoelectron spectroscopy confirmed a non‐covalent mixture of LIG and Tri‐MOF. Compared with the negligible activity of LIG alone, low doses (0.91‐4.54 mg/mL) of the prepared LIG/Tri‐MOF composite showed excellent antibacterial activity (≥ 95% bacterial removal) and a MIC of 0.6 mg/mL, for Gram‐negative bacteria via the gradual leaching of metal ions and organic linker from the material enhanced by bacterial aggregation near the LIG/Tri‐MOF. Compared to a mixture of separately synthesized Tri‐MOF and LIG, the LIG/Tri‐MOF composite showed improved antibacterial effects. All materials showed cytotoxicity for L929 mouse cell lines, the solids showing a disrupting effect on cells grown in vitro. Performance‐enhancing combinations of various materials leading to synergistic or additive antimicrobial effects is an essential strategy for minimizing the possible emergence of antibiotic‐resistant strains.This article is protected by copyright.

In this investigation, nanoparticles such as ZnO, Fe doped ZnO and Co doped ZnO NPs prepared by the co-precipitation method were tested against the pathogenic yeast. The spectroscopic analyses were carried out to identify the morphological and chemical composition of the synthesized nanoparticles. The results of XRD analysis revealed that the synthesized nanoparticles were crystalline in nature with average size ranges between 32 – 34 nm approximately. EDX and SEM analysis were carried out to identify the element composition (Co, Fe and Zn) and spherical shape of nanoparticles. The functional group that is responsible for the capping and stability of nanoparticles was confirmed by FTIR analysis, to compare the antifungal efficiency of ZnO, Fe doped ZnO and Co doped ZnO from the resultant zone of inhibition.
