Metal Nanoparticles have attracted considerable attention because of their excellent electronic and optical properties. They have been used in many fields, such as displays, solar cells, touchscreens, sensors, and electromagnetic interference shielding [1]. However, for most of these applications, metal Nanoparticles with high electrical conductance are required. Compared with various other met...

objective(s): this study focused on determining cytotoxic effects of copper oxide nanoparticles (cuo nps) on chronic myeloid leukemia (cml) k562 cell line in a cell-specific manner and its possible mechanism of cell death. we investigated the cytotoxicity of cuo nps against k562 cell line (cancerous cell) and peripheral blood mononuclear cell (normal cell). materials and methods: the toxicity w...

Nanoparticles (NPs) have received more attention as antiparasitic agents. In the present study, silver and copper nanoparticles were synthesized and characterized using scanning electron microscopy (SEM), transmission electron microscope (TEM) and X-ray fluorescence (XRF). The antiparasitic activity of Ag and CuO nanoparticles were tested against two of the most environmentally spread parasites...

Objective(s): CuO is one of the most important transition metal oxides due to its captivating properties. It is used in various technological applications such as high critical temperature superconductors, gas sensors, in photoconductive applications, and so on. Recently, it has been used as an antimicrobial agent against various bacterial species. Materials and Methods: Here, we synthesized Cu...

Copper ions are an effective antimicrobial agent used to control Legionnaires' disease and Pontiac fever arising from institutional drinking water systems. Here, we present data on an alternative bactericidal agent, copper oxide nanoparticles (CuO-NPs), and its efficacy on Legionella pneumophila. In broth cultures, the CuO-NPs caused growth inhibition, which appeared to be concentration and exp...

STATEMENT OF PROBLEM Acid producing bacteria including Streptococcus mutans and lactobacilli cause tooth demineralization and lead to tooth decay. Also, oral colonization of the species of Candida has been reported in many studies that are resistant to antifungal agents. OBJECTIVES In this study, antibacterial and antifungal effects of nano-CuO were studied against some oral bacteria and yeas...

Copper oxide nanoparticles (CuO NPs) are used for a variety of purposes in a wide range of commercially available products. Some CuO NPs probably end up in the aquatic systems, thus raising concerns about aqueous exposure toxicity, and the impact of CuO NPs on liver development and neuronal differentiation remains unclear. In this study, particles were characterized using Fourier transform infr...

This study proposes a molecular mechanism for lung epithelial A549 cell response to copper oxide nanoparticles (CuO-NPs) related to Cu ions released from CuO-NPs. Cells that survived exposure to CuO-NPs arrested the cell cycle as a result of the downregulation of proliferating cell nuclear antigen (PCNA), cell division control 2 (CDC2), cyclin B1 (CCNB1), target protein for Xklp2 (TPX2), and au...
