【 摘 要 】

Copper-based particles were synthesized using an electroless deposition technique. The said synthesis was done in an aqueous solution by reducing copper oxide powders using hydrazine. In this technique, gelatin was used as protective agent. X-ray Diffraction (XRD) measurement shows that the synthesized sample is composed of cuprous oxide (Cu2O) and copper (Cu) particles. Scanning Electron Microscopy (SEM) shows the morphology of the synthesized copper-based particles. Antimicrobial test shows that the number of Escherichia coli organisms reduced to 62.06% after 2 minutes of contact with the sample. Likewise, SEM micrographs of the Escherichia coli organisms show that the said organism underwent morphological changes in the presence of the synthesized copper-based particles.
