Investigation of the Antimicrobial Activity and Hematological Pattern of Nano-Chitosan and its Developed Nano-Copper Composite

Abstract

Novel synthesized Chitosan-Copper oxide nanocomposite (Cs-CuO) was prepared using pomegranate peels extract as green precipitating agents to improve the biological activity of Cs-NP's which was synthesized through ionic gelation method. The characterization of biogenic nanoparticles Cs-NP's and Cs-CuO-NP's were investigated structurally, morphologically to determine the full descriptive features of those nanoparticles. Antimicrobial activity was tested for both Cs-NP's and Cs-CuO-NP's via Minimum inhibition concentration and zone analysis against fungus, gram positive and gram negative. The results of the antimicrobial test showed high sensitivity of Cs-CuO-NP's to all microorganisms that are tested in concentration less than 20 mg/ml while the sensitivity of Cs-NP's against all microorganisms under test started from a concentration of 20 mg/ml to 40 mg/ml except for the C.albicans species. Hematological activity was also tested in via measuring the RBCs, platelets count and clotting time against healthy, diabetic and hypercholesterolic blood samples. Measurement showed a decrease in RBCs and platelets count by adding Cs-NP’s or Cs-CuO-NP's to the three blood samples. Cs-NP’s success to decrease the clotting time for healthy and diabetic blood acting as a procoagulant agent, while adding biogenic CuO-NP’s to Cs-NP’s increased clotting time considering as an anticoagulant agent for hyperchloesterolic blood samples.
