“…Considering the Raman shift difference that is inferred to size or strain/stress effects, the position and relative intensities of the peaks are in good agreement with the reported values of the NiO phase. 62 , 63 Moreover, the chemical composition and oxidation state of the prepared NiO NPs sample were explored by the XPS ( Figure 2 a–d). The XPS survey spectra of the sample showed the peaks for the nickel (Ni), oxygen (O), and carbon (C) atoms confirming the presence of main elements as Ni, O, and C ( Figure 2 a).…”

The present work demonstrated a novel Cleome simplicifolia -mediated green fabrication of nickel oxide nanoparticles (NiO NPs) to explore in vitro toxicity in Bm-17 and Labeo rohita liver cells. As-fabricated bioinspired NiO NPs were characterized by several analytical techniques. X-ray diffraction (XRD) revealed a crystalline face-centered-cubic structure. Fourier transform infrared spectroscopy (FTIR), ultraviolet–visible diffuse reflectance spectroscopy (UV-DRS), Raman spectroscopy, and X-ray photoelectron spectroscopy (XPS) confirmed NiO formation. The chemical composition was confirmed by energy-dispersive X-ray spectroscopy (EDS) and X-ray photoelectron spectroscopy. Brunauer–Emmett–Teller (BET) revealed the mesoporous nature. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) revealed the formation of 97 nm diameter nanospheres formed due to the congregation of 10 nm size particles. Atomic force microscopy (AFM) revealed the nearly isotropic behavior of NiO NPs. Further, a molecular docking study was performed to explore their toxicity by binding with genetic molecules, and it was found that the docking energy was about −9.65284 kcal/mol. On evaluating the in vitro toxicity of NiO NPs for Bm-17 cells, the study showed that when cells were treated with a high concentration of NPs, cells were affected severely by toxicity, while at a lower concentration, cells were affected slightly. Further, on using 50 μg/mL, quick deaths of cells were observed due to the formation of more vacuoles in the cells. The DNA degradation study revealed that NiO NPs are significantly responsible for DNA degradation. For further confirmation, trypan blue assay was observed for cell viability, and morphological assessment was performed using inverted tissue culture microscopy. Further, the cytotoxicity of NiO NPs in L. rohita liver cells was studied. No toxicity was observed at 1 mg/L of NiO NPs; however, when the concentration was 30 and 90 mg/L, dark and shrank hepatic parenchyma was observed. Hence, the main cause of cell lysis is the increased vacuolization in the cells. Thus, the present study suggests that the cytotoxicity induced by NiO NPs could be used in anticancer drugs.

“…Spinel aluminate is a wide-gap semiconductor, such as BeAl 2 O 4 (6.450 eV) (Ching et al, 2001), MgAl 2 O 4 (3.923 eV) (Wang et al, 2019a), CaAl 2 O 4 (7.400 eV) (Moirangthem et al, 2019), SrAl 2 O 4 (3.984 eV) (Shifa , BaAl 2 O 4 (3.910 eV) (Nair and Pillai, 2021), MnAl 2 O 4 (4.030 eV) (Bhavani et al, 2018), FeAl 2 O 4 (1.780 eV) (Mu et al, 2017), CoAl 2 O 4 (1.948 eV) (Gao et al, 2018), NiAl 2 O 4 (3.000 eV) (Chellammal Gayathri et al, 2021), CuAl 2 O 4 (2.920 eV) (Potbhare et al, 2019), and ZnAl 2 O 4 (3.800 eV) (Shang-Pan et al, 2020). Based on the obtained optical band gap value and band theory, the conduction band potential and valence band potential of MAl 2 O 4 were calculated.…”

Photocatalysis is regarded as a green technology to degrade organic dyes driven by light energy. The selection of photocatalyst restricts the development of photocatalytic technology. Aluminate is a kind of potential broad-gap semiconductor photocatalyst and also an excellent phosphor substrate materials. The physical and chemical properties of aluminate are strongly dependent on the preparation method. Insight into the influence of synthesis methods on photocatalytic activity of aluminate based photocatalysts is helpful for the development of novel aluminate based photocatalysts. In this paper, the typical synthesis methods of aluminate photocatalysts, ion-doped aluminate based photocatalysts and heterojunction type aluminate photocatalysts, and their photocatalytic activities are reviewed. Based on the energy band theory, the photocatalytic mechanisms of single component aluminate photocatalyst, ion-doped aluminate based photocatalyst, and heterojunction type aluminate photocatalyst were reviewed. The future development of aluminate based photocatalyst will give priority to the salinization of aluminate modified by silver and other metal particles and the photocatalytic application of activated ion modified aluminate based phosphors.

“…However, concerns about the antibiotic resistance, pollution, high cost, and complexity of the production process are major disadvantages of these materials [156]. Recently published data revealed that metal/metal oxide NPs could be used as an excellent antibacterial agents [157,158]. Very recently, graphene [159] paper was used as biocompatible substrate for adhesion and proliferation of different cells, for example L-929 cells, neuroendocrine PC12 cells, oligodendroglia cells, and osteoblasts, where GO nanocarriage was used to deliver water-insoluble drugs into cells.…”

Metal oxides and their nanocomposites are used in various technological applications. Biofabrication of carbon-based metal oxide nanocomposites preparation using plants, microbes, cell cultures and enzymes are the most attractive technique because of nontoxic nature, and sustainable process. Phytochemicals play important role in size lessening of the particles by performing as structure-directing, capping and reducing agents. In this chapter, we shed light on eco-friendly, money-spinning, and phytosynthesis of carbon based nanomaterials (CNMs) like graphene oxide, reduced graphene oxide, and metal doped-rGO nanocomposites using green reducers. Moreover, electrochemical, photocatalytical and biological applications of CNMs and their nanocomposites with metal oxides are discussed.
