“…Semiconductors TiO 2 and ZnO attract light energy in the UV range because of their large bandgap and high stability, rendering them suitable for UV screening applications [ 15 ]. The bactericidal mechanism of ZnO or TiO 2 NPs have been suggested due to the generation of reactive oxygen species (ROS) on the bacterial cell membrane, altering the metabolic functions and thus leads to the bacterial cell inactivation [ 16 ]. It was also suggested that the nanoparticles could have undergone internalisation through the cell membrane damage, which could efficiently kill the bacterial pathogens [ 17 , 18 ].…”

This paper presents for the first time a successful fabrication of ternary ZnO/TiO2/Ag nanocomposites consisting of zinc oxide (ZnO), titania (TiO2) and silver (Ag) nanoparticles (NPs) synthesised using Morinda citrifolia fruit (MCF) extract. ZnONPs were synthesised using the co-precipitation method, and TiO2 and Ag were introduced into the precursor solutions under microwave irradiation to obtain ZnO/TiO2/Ag nanocomposites (NCs). This material demonstrated enhanced bactericidal effect towards bacterial pathogens compared to that of the binary TiO2/Ag, Ag and TiO2 alone. In vitro cytotoxicity results of the as-synthesised ZnO/TiO2/AgNCs on RAW 264.7 macrophages and A549 cell lines revealed a negative role in cytotoxicity, but contributed astoundingly towards antimicrobials as compared of Ag alone and binary Ag/TiO2. This study shows that the resultant ternary metal/bi-semiconductor nanocomposites may provide a therapeutic strategy for the eradication of bacterial pathogens without affecting the healthy mammalian cells.

“…Photocatalysts are very promising when it comes to the decomposition and removal of organic pollutants and microorganisms in wastewater [5,8]. As it has been shown, photocatalytic treatment of wastewater can also eliminate loads of microbiological contaminations that may transmit infectious disease [9,10]. Among different photocatalyst compounds, TiO 2 is the first and still one of the most widely used ones.…”

This paper investigates the photocatalytic characteristics of Ag nanowire (AgNW)/TiO2 and AgNW/TiO2/graphene oxide (GO) nanocomposites. Samples were synthesized by the direct coating of TiO2 particles on the surface of silver nanowires. As-prepared AgNW/TiO2 and AgNW/TiO2/GO nanocomposites were characterized by electron microscopy, X-ray diffraction, UV/visible absorption spectroscopy, and infrared spectroscopy. Transmission electron microscope (TEM) images confirmed the successful deposition of TiO2 nanoparticles on the surface of AgNWs. The photocatalytic activity of synthesized nanocomposites was evaluated using Rhodamine B (RhB) in an aqueous solution as the model organic dye. Results showed that synthesized AgNW/TiO2/GO nanocomposite has superior photocatalytic activities when it comes to the decomposition of RhB.

“…Furthermore, the electrostatic attraction between GO and human amino acids persuades the progress of the osteogenesis process [32][33][34]. Further, Hajipour et al, investigated the antibacterial properties of CuO, CuO-GO, and CuO-GO-Ag nanocomposites [35]. Germicidal behavior of the previously mentioned compositions was inspected against Gram-positive Staphylococcus aureus and Gramnegative Escherichia coli by the disc diffusion technique.…”

“…Minor addition of GO caused fewer aggregations of prepared composites. CuO-GO-Ag nanocomposite displayed significant enhancement in antibacterial performance against the tested bacteria, resulting in a higher inhabitation zone compared to CuO and CuO-GO composites [35]. Additionally, Ashraf et al stated that GO addition to hybrid metal sulfide/ oxide nanocomposites (NiS-MoO 3 ) enhances antibacterial and antioxidant performance [36].…”

Nanocomposites based on hydroxyapatite (HAP), including MoO 3 , HAP/MoO 3 , HAP/GO and HAP/MoO 3 /GO have been studied to be suggested for biological usage. The different compositions were investigated using FTIR, XRD, EDS, and XPS analysis. The tight relation between morphological features and composites' chemical ingredients was also studied. According to TEM micrographs, it was mentioned that the disappearance of well-defined grains after the combinations of HAP and MoO 3 , while graphene oxide (GO) caused a reduction in size and maintaining the particles' shape. The combination between HAP/MoO 3 declines the roughness of both HAP and MoO 3 individually, recording 27.5 nm, while HAP/GO and HAP/MoO3/GO exhibit in-between roughness average (Ra) value among its raw constituents with 34.7 and 33.5 nm, respectively. Furthermore, SEM micrographs and roughness results show how to tailing the proper features for the proposed application by changing the type and amount of additives into HAP. Thus, the composite (HAP/MoO 3 /GO) displays the uppermost cell viability compared with the rest compositions with 97.8 ± 3.0%. Additionally, this triple composite hits the peak germicidal behavior with 17.9 ± 1.2 and 16.5 ± 0.9 mm against both E.coli and S.aureus, respectively.
