Abstract
BackgroundMany cancer patients suffer from cancer-related life-threatening infections due to immune system damage. Therefore, researchers are continuously looking for new options to treat cancer-related infections. As nanotechnology has gained tremendous interest over the past several decades, silver nanoparticles have been investigated as an effective antimicrobial agent. Here, silver-coated gold nanorods were synthesized to share similar optical properties as gold nanopar-ticles for cancer diagnosis and treatment, with an added advantage of antibacterial properties.ResultsTheir dose-dependent antimicrobial properties were demonstrated on both Gram-negative and Gram-positive bacteria species. These nanorods were found to be highly efficient in killing bacteria and suppressing biofilm formation.ConclusionCollectively, such results suggest that silver-coated gold nanorods should be further investigated as a novel material, which can both decrease cancer cell functions and reduce the risk of infection for cancer patients.
