Morphology-dependent antibacterial activities of Cu 2O
Cubic and octahedral Cu 2O microcrystals were synthesized by the reduction of a copper–ligand complex solution with glucose under microwave irradiation using ethylenediaminetetraacetic acid (EDTA) and N,N,N′,N′-tetramethyl ethylenediamine (TMEDA) as ligands. Scanning electron microscopy (SEM) and X-...

Summary: | Cubic and octahedral Cu
2O microcrystals were synthesized by the reduction of a copper–ligand complex solution with glucose under microwave irradiation using ethylenediaminetetraacetic acid (EDTA) and N,N,N′,N′-tetramethyl ethylenediamine (TMEDA) as ligands. Scanning electron microscopy (SEM) and X-ray diffraction (XRD) confirmed that the surfaces of the cubic and octahedral of Cu
2O microcrystals had {100} and {111} lattice planes. The antibacterial activity of the Cu
2O microcrystals against
E. coli was examined using optical density (OD) methods. The antibacterial activity of the cubic Cu
2O crystals was superior to that of the octahedral Cu
2O crystals. The mechanism of the specific morphology-controlled synthesis of Cu
2O and their morphology-dependent antibacterial activity are discussed. |
