“…The bimetallic system Pd/Ag has also recently been the subject of antibacterial activity in nanoparticle form. , However, it should be noted that studies involving atomically precise NC, which have fully identified structural features, are exceedingly rare in the literature. The critical factor to the antibacterial activity has been the ability to release Ag + at a specific rate and location .…”

The first hydride-doped Pd/Ag superatoms stabilized by selenolates are reported: [PdHAg 19 (dsep) 12 ] [dsep = Se 2 P(O i Pr) 2 ] 1 and [PdHAg 20 (dsep) 12 ] + 2. 1 was derived from the targeted transformation of [PdHAg 19 (dtp) 12 ] [dtp = S 2 P(O i Pr) 2 ] by ligand exchange, whereas 2 was obtained from the addition of trifluoroacetic acid to 1, resulting in a symmetric redistribution of the capping silver atoms. The transformations are all achieved while retaining an 8-electron superatomic configuration. VT-NMR attests to the good stability of the NCs in solution, and single-crystal X-ray diffraction reveals the crucial role that the interstitial hydride plays in directing the position of the capping silver atoms. The total structures are reported alongside their electronic and optical properties. 1 and 2 are phosphorescent with a lifetime of 73 and 84 μs at 77 K, respectively. The first antibacterial activity data for superatomic bimetallic Pd/Ag nanoclusters are also reported.

“…[5] Therefore, bimetallic nanoparticles, their composites, [9,10] and multielement metal nanoparticle compositions have been demonstrated to have enhanced antibacterial efficacy and eliminate a wide variety of bacteria. [11,12] The release of specific metal ions from these multielement metal nanoparticles was demonstrated to be toxic to bacteria. [13] Various inexpensive organic polymers and metal-containing materials have been used to develop alternative antibacterial materials.…”

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.

“…This process is known as a "core-shell" formation. Also, the shell layer could improve the physiochemical properties of the core material, like its catalytic activity and nonlinear properties 9 , leading to new, unique properties that could speed up development in several application fields 10,11 .Research interest in zinc oxide (ZnO) has been increasing, particularly in nanotechnology, to synthesize ZnO on a nanoscale because of its properties and applications [12][13][14][15] . It is crucial in the creation of possible antimicrobial drugs as well as in scientific and technological fields such as nonlinear optics, electrical devices, catalysis, and medicinal applications for their having a large surface area and high crystallinity 16,17 .…”

Given their versatile nature and wide range of possible applications, core–shell nanoparticles (NPs) have received considerable attention. This paper proposes a novel method for synthesizing ZnO@NiO core–shell nanoparticles using a hybrid technique. The characterization demonstrates the successful formation of ZnO@NiO core–shell nanoparticles, which have an average crystal size of 13.059 nm. The results indicate that the prepared NPs have excellent antibacterial activity against both Gram-negative and Gram-positive bacteria. This behavior is primarily caused by the accumulation of ZnO@NiO NPs on the bacteria's surface, which results in cytotoxic bacteria and a relatively increased ZnO, resulting in cell death. Moreover, the use of a ZnO@NiO core–shell material will prevent the bacteria from nourishing themselves in the culture medium, among many other reasons. Finally, the PLAL is an easily scalable, cost-effective, and environmentally friendly method for the synthesis of NPs, and the prepared core–shell NPs could be used in other biological applications such as drug delivery, cancer treatment, and further biomedical functionalization.
