Preparation of Ag@CNT Nanohybrids and Investigations on Their Antibacterial and Cytotoxicological Effects
The cytotoxicological effects of carbon nanotubes (CNTs) decorated with Ag nanoparticleve has not been rigorously studied. In the present research, Ag@CNT nanohybrids were prepared using the aqueous reduction method. Glucose and cetyltrimethyl ammonium bromide were used as the reducing
agent and stabilizer, respectively. The morphologies and structures of the Ag@CNT nanohybrids were characterized in detail. Bactericidal tests were performed in an ordinary broth medium on solid agar plates with Ag@CNTs. The MC3T3-E1 cells were also cultured with the composites to determine
the cytotoxicological effects of Ag@CNTs. The results showed that the Ag nanoparticles were distributed uniformly on the CNT surface or interior. Ag nanoparticles were short rod-like crystals with a diameter of 3.7 ± 0.2 nm. The constructs showed strong antibacterial effects on both
Gram-negative (Escherichia coli) and positive (Staphylococcus aureus) bacteria. The cytological experiments demonstrated that Ag@CNT nanohybrids displayed cytocompatibility and did not exhibit negative effects on the cells.
