Synergistic effect of ZnO nanoparticles with Cu2+ doping on antibacterial and photocatalytic activity

Plant extract mediated synthesis of ZnO and CeO2 nanoparticles for spectrofluorometric assay of omeprazole and domperidone in pharmaceuticals

“…5 a shows the correspondence between the diffractogram of ZnONPs and the standard XRD curve of ZnO (JCPDS card No-36-1451), The peaks corresponding to 2θ values of 31.64° (1 0 0), 34.43° (0 0 2), 36.29° (1 0 1), 47.75° (1 0 2), 56.51° (1 1 0), 62.90° (1 0 3), 67.98° (1 1 2) and 69.23° (2 0 1). Which shows the high purity of the synthesized nanoparticles [ 52 ]. These values closely match the wurtzite structure of ZnO.…”

Data-Driven Machine Learning to Predict Antibacterial Activity of Cerium-Doped Nanoparticles

“…16,17 In addition, most of these experiments are qualitative, reporting the zone of inhibition values without exhaustive statistical analyses to demonstrate the antibacterial activity. 18,19 Cerium-based nanoparticles have reached interest due to their bioactivity and abundance. 20−22 The results of improvement in antibacterial activity are still controversial.…”

“…The antibacterial properties of ZnO are related to grain size, and when it is doped with different chemical elements, these properties are also associated with the optical band gap . In recent years, lanthanide elements such as La, Ce, and Nd were used to tailor the optical band; consequently, the antibacterial properties have been improved. − However, in many cases, these results were derived from the photocatalytic process due to the exposition of the nanoparticles and bacteria to UV light. , In addition, most of these experiments are qualitative, reporting the zone of inhibition values without exhaustive statistical analyses to demonstrate the antibacterial activity. , Cerium-based nanoparticles have reached interest due to their bioactivity and abundance. − The results of improvement in antibacterial activity are still controversial.…”
