Review on Zinc Oxide Nanoparticles: Antibacterial Activity and Toxicity Mechanism.
Amna Sirelkhatim,Shahrom Mahmud,Azman Seeni,Noor Haida Mohamad Kaus,Ling Chuo Ann,Siti Khadijah Mohd Bakhori,Habsah Hasan,Dasmawati Mohamad +7 more
TL;DR: This review covered ZnO-NPs antibacterial activity including testing methods, impact of UV illumination,ZnO particle properties (size, concentration, morphology, and defects), particle surface modification, and minimum inhibitory concentration.
Journal ArticleDOI

Ling Chuo Ann,Shahrom Mahmud,Siti Khadijah Mohd Bakhori,Amna Sirelkhatim,Dasmawati Mohamad,Habsah Hasan,Azman Seeni,Rosliza Abdul Rahman +7 more
TL;DR: In this paper, the antibacterial responses of zinc oxide (ZnO) structures against Staphylococcus aureus, Pseudomonas aeruginosa, and Streptococcus pyogenes were investigated.
Journal ArticleDOI
Preferential cytotoxicity of ZnO nanoparticle towards cervical cancer cells induced by ROS-mediated apoptosis and cell cycle arrest for cancer therapy
TL;DR: Results exposed the impact of size and morphology of ZnO samples on their toxicity to Hela cells mediated mainly by ROS production, and synergistic effect ofZnO-NPs size (20, 40, 80 nm) and nanostructure (nanorods, nanogranules) impacted the inhibition of HeLa cells growth and eventually death.
Journal ArticleDOI
Effect of surface modification and UVA photoactivation on antibacterial bioactivity of zinc oxide powder
Ling Chuo Ann,Shahrom Mahmud,Siti Khadijah Mohd Bakhori,Amna Sirelkhatim,Dasmawati Mohamad,Habsah Hasan,Azman Seeni,Rosliza Abdul Rahman +7 more
TL;DR: In this paper, the effects of surface modification of zinc oxide (ZnO) powder and UVA illumination on the powder towards Escherichia coli and Staphylococcus aureus were investigated.
Journal ArticleDOI
Structural morphology and in vitro toxicity studies of nano- and micro-sized zinc oxide structures
Ling Chuo Ann,Shahrom Mahmud,Azman Seeni,Siti Khadijah Mohd Bakhori,Amna Sirelkhatim,Dasmawati Mohamad,Habsah Hasan +6 more
TL;DR: The structural morphology and in vitro toxicity of nano-and micro-sized ZnO structures were investigated in this paper, where all the samples were characterized to determine their morphologies, particle sizes, structures and optical bandgaps.
