“…Simultaneously, the level of superoxide increased in the cytoplasm, which may be related to CdSe QDs formation in F. oxysporum (Yamaguchi et al, 2016). Diko et al (2020) fabricated 10-30 nm cubic-face centered PbSe nanoparticles using Trichoderma sp. WL-Go under optimum reaction conditions of pH 8 with 0.5 g biomass and 1:1 mM of SeO 2 :Pb(NO 3 ) 2 and further studied their antioxidant and photocatalytic activity.…”

“…Biological entities such as fungi, bacteria, and yeasts produce nanoparticles as part of their defense mechanisms against environmental pollutants, particularly metals (see Chapter 3). They reduce metal toxicity by coupling them to biological molecules by metal-dependent enzymes, transporters, metal ion regulators, ligands or other binding proteins (Diko et al, 2020;Iravani, 2014;Shao et al, 2018). Further, this reduction of metal ions can result in metal precipitation as a nanomaterial in the microorganism's intra or extracellular spaces.…”

“…The existence of biomolecules on the biogenic nanoparticles' surface eliminates the additional step of functionalization for certain biomedical applications. Hence, metal selenide nanoparticles find application in specific fields, especially bioimaging and biolabeling, therapeutic agents (Mal et al, 2016), antimicrobials (Jacob et al, 2016) and catalytic applications for removing pollutants from the environment (Diko et al, 2020).

Semiconductors are characterized by an electronic band structure in which the highest-occupied energy band, called the valence band (VB), and the lowest-occupied energy band, called the conduction band (CB), are separated by a bandgap, that is, a region of forbidden energies (Liqiang et al., 2006). In recent years, semiconductor nanostructures have gained interest due to their applications in various fields including solar cells, laser technology, light-emitting diodes, nanoscale electronic devices, components of armor, parts of automobiles, superabsorbents, packaging films, catalysis, and biosensors. Semiconductor nanocrystals such as silicon and germanium belong to group IV; gallium nitride (GaN), gallium phosphide (GaP), gallium arsenide (GaAs), indium phosphide (InP), and indium arsenide (InAs) belong to group III-V, while zinc oxide (ZnO), zinc sulfide (ZnS), cadmium sulfide (CdS), cadmium selenide (CdSe) and cadmium telluride (CdTe) belong to group II-VI of the periodic table (Suresh, 2013).Among the semiconductors, selenium (Se) is an attractive material with intriguing physical and chemical properties. It has photoconductive features with

“…With the textile industry having about 60-70% usage of all available commercial dye products (Saggioro et al, 2011), the dye pollutants from these industries tend to contaminate the environment especially water bodies; when they are indecorously disposed-of (Habib et al, 2013;Rahman et al, 2014;Rezig & Hadjel, 2014). Furthermore, recent advances in environmental remediation strategies such as photocatalysis and flocculation have been researched as an alternative technique for purification of dye-polluted water (Agbe et al, 2018;Diko et al, 2020). Photocatalysis using porous nanostructured semiconducting transition metal oxide photocatalysts such as TiO 2 , SnO (Byberg et al, 2013), ZnO and Cu 2 O (Agbe et al, 2019) seem to be the most suitable approach due to the fact that these photocatalysts are energetically sustainable, and can be easily used in combination with other catalysts.…”

Synthesis of nanostructured cupric oxide for visible light assisted degradation of organic wastewater pollutants

When organic dye-containing wastewater from textile industries are sometimes released into the environment, the liquids tend to pollute the environment whilst their solid residue accrues on land after the evaporation of the water. Most of these synthetic compounds are known to be poisonous and carcinogenic to living organisms. For this study, a relatively simple, sustainable and cost-effective approach have been utilized to synthesize CuO nanoparticles using copper precursor salts: (CuSO 4 .5H 2 O) and (Cu(NO 3 ) 2 .3H 2 O), as a remedy for dye pollution reduction in water. Due to their simplicity of synthesis, insignificant harmfulness and cost, copper (II) oxide (CuO) nanoparticles were used to breakdown three generally utilized dyes; Rhodamine B (RhB), Methylene Blue (MB)-[Methylthioninium chloride] and Methyl Orange (MeO). The as-prepared nanoparticles were characterized to

In this study, we aimed to improve the delivery and efficacy of the well‐known anticancer drug, tamoxifen (TAM), through its encapsulation in bovine serum albumin nanoparticles (BSA NPs) and their hybridization with selenium nanoparticles (Se NPs). The developed nanostructures were characterized by Fourier transform infrared (FT‐IR) spectroscopy, ultraviolet–visible (UV–Vis) spectroscopy, energy‐dispersive X‐ray spectroscopy (EDS) analysis, dynamic light scattering (DLS), and field emission scanning electron microscopy (FESEM) imaging. The impact of nanostructures on 4T‐1 cancer cells was assessed through MTT and flow cytometry assays to measure cytotoxicity and apoptosis rates, respectively. FT‐IR and UV–Vis spectroscopy confirmed the successful encapsulation of TAM within BSA NPs. EDS analysis confirmed the Se integration into BSA‐TAM@Se NPs, signifying successful hybridization. Size and zeta potential measurements revealed the average hydrodynamic size and surface charge of the nanostructures. BSA NPs, BSA@Se NPs, and Se NPs showed the sizes ranging from 153.37 ± 1.02 to 229.63 ± 1.36 nm, with zeta potential values from −10.12 ± 0.26 to −28.45 ± 0.40 mV. Hemocompatibility studies demonstrated minimal hemolytic activity of the nanostructures, indicating their biocompatibility for intravenous administration. Cellular toxicity assays showed higher cytotoxicity of BSA‐TAM@Se NPs compared to other formulations (****p < 0.0001). The increased cell death in 4T‐1 breast cancer cells highlights the enhanced therapeutic potential of BSA‐TAM@Se NPs. Apoptosis analysis revealed a significant increase in apoptosis rate in 4T‐1 cells treated with BSA‐TAM@Se NPs compared to other formulations (****p < 0.0001), emphasizing their ability to induce programmed cell death. These findings support the rational importance of BSA NPs as drug nanocarriers and their hybridization with Se NPs to improve therapeutic effects. Finally, we suggest that the developed BSA‐TAM@Se NPs can be used as a potential therapeutic approach in combination with other tools such as X‐ray irradiation in future studies.
