Photocatalytic and bactericidal properties and molecular docking analysis of TiO₂nanoparticles conjugated with Zr for environmental remediation

Abstract

Despite implementing several methodologies including a combination of physical, chemical and biological techniques, aquatic and microbial pollution remains a challenge to this day.

Algae-mediated route to biogenic cuprous oxide nanoparticles and spindle-like CaCO3: a comparative study, facile synthesis, and biological properties

“…Nanostructured materials have received a considerable attention for their antibacterial and biological properties in the recent years. [28][29][30][31]58 Due to their high potential and advantages such as long shelf life over common antibiotics and cytotoxic compounds many studies conducted on nanostructured copper-based particles. [59][60][61] The antibacterial activity of other forms of copper-based nanoparticles was veried in previous studies, and researches conrm the effect of nanoparticle size on antibacterial activity.…”

“…64 Ikram et al have recently investigated the antibacterial activity of a variety of copper-assisted nanoparticles. 28,35,65 They have stated that Cudoped ZnO nanorods as antibacterial agent produce reactive oxygen species (ROS) on the bacterial cell membrane, which resulted in the extrusion of cytoplasmic contents and the bacteria death. They have also suggested another possible mechanism for the action of nanomaterials antibacterial in which the cations (Cu 2+ and Zn 2+ ) form strong interactions with the negatively charged parts of the bacterial cell membrane, which leads to a collapse of the micro pathogens.…”

“…In recent years, various applications for nanostructured materials have been reported. 28,29 The nanomaterials have shown signicant potential for use in bactericidal applications. 28,[30][31][32] Multidrug resistance (MDR) is growing in both Gram positive and Gram negative bacteria and is compromising the effectiveness of antibiotic therapy especially by increasing the healthcare associated infections (HAIs) causing several thousands of deaths annually.…”

Development of Multi-Concentration Ag:Cu Bimetallic Nanoparticles as a Promising Bactericidal for Antibiotic-Resistant Bacteria as Per Molecular Docking Exploration

“…Based upon its structure such as core-shell, dumb-bell structure, two interface structure, randomly mixed structure, and ower shape structure, various types of bimetallic NPs exhibit antimicrobial activity [27][28][29][30][31]. There are various methods for synthesis of bimetallic NPs including co-precipitation method, sol-gel method, hydrothermal method, reduction method, microemulsion method, and polyol method [32][33][34][35][36][37].…”
