Copper nanoparticles and their oxides: optical, anticancer and antibacterial properties

Albumin-coated copper nanoparticles for photothermal cancer therapy: Synthesis and in vitro characterization

“…There is growing evidence regarding various bioactivities of the CuNPs, such as anti-microbial, anti-viral, and anticancer activity [ 31 ]. Regarding specifically the anticancer activity of the CuNPs, the BSA-CuNPs are known to induce apoptosis by causing oxidative stress on the DNA and mitochondria [ 49 ]. The anticancer effects of the BSA-CuNPs were not limited to specific cancer cells but were commonly found in various cancer cells [ 50 ].…”

Microbial synthesis of titanium dioxide nanoparticles and their importance in wastewater treatment and antimicrobial activities: a review

“…The metallic NPs include both metal oxides and metal NPs, whereas the metal NPs mainly include gold (Au), silver (Ag), Ti, platinum (Pt), copper (Cu), and Fe (0). The metal oxide NPs include titanium dioxide (TiO 2 ) (Kiwi et al, 2014 ), zinc oxide (ZnO) (Modi et al, 2022a , 2023b ; Onyszko et al, 2022 ), iron oxide (Fe 2 O 3 /Fe 3 O 4 ) (Pan et al, 2022 ; Yadav et al, 2023a ), magnesium oxide (MgO) (Dabhane et al, 2022 ), copper oxide (CuO) (Maliki et al, 2022 ), alumina (Al 2 O 3 ), and many more (Ravichandran, 2010 ; Guerra et al, 2018 ). Among non-metallic ones, the most prominent are silica oxide (SiO 2 ) (Huang et al, 2022 ; Imoisili and Jen, 2022 ; Imoisili et al, 2022 ; Yadav et al, 2023c ), graphene, and carbon nanotubes (CNTs) (Guerra et al, 2018 ).…”

Drug-Free Hybrid Nanoarchitecture Modulation of the Metastatic Behavior of Pancreatic Ductal Adenocarcinoma in Alternative in Vivo Models

“…In particular, several Cu complexes have been developed to affect DNA, topoisomerase I–II, proteasome, and cellular metabolism . Some copper and copper oxide nanoparticles (CuNPs and CuONPs) have been explored as anticancer agents able to promote the production of reactive oxygen species (ROS) and the cascade of events that results in cell death. − Moreover, an antimetastatic effect of some CuNPs/CuONPs and copper complexes is also reported on various cancer lines. ,− Copper is more cytotoxic for cancerous than healthy cells, even though a detailed biological safety investigation is still lacking . Indeed, it should be noted that copper ions released from CuNPs may interact with cysteine and methionine residues in proteins, potentially affecting their biological safety.…”
