Staphylococcus aureus (S. aureus) is the most common reason behind bacterial infections in humans. They cause a wide array of infections on skin, bone and joint medical implants and blood stream. In order to mitigate these infections, detecting the presence of this bacterium is of prime importance. This paper explores a new rapid detection technique to identify S aureus bacteria. A screen-printed sensor coated with graphene oxide was used as an identification platform. Graphene oxide was synthesized using modified Hummer’s method and was characterized using X-ray Diffractometer and Scanning Electron Microscope. The developed sensors showed significant decrease in the bulk resistance with the increase in bacterial concentrations. The developed sensors were subjected to selectivity, repeatability and reusability tests and showed good results.

使用氧化石墨烯涂层的丝网印刷传感器条快速检测金黄色葡萄球菌

金黄色葡萄球菌（S. aureus）是人类细菌感染背后的最常见原因。它们在皮肤，骨骼和关节的医疗植入物和血液中引起多种感染。为了减轻这些感染，检测该细菌的存在是最重要的。本文探索了一种新的快速检测技术来鉴定金黄色葡萄球菌菌。涂有氧化石墨烯的丝网印刷传感器用作识别平台。使用改进的Hummer方法合成氧化石墨烯，并使用X射线衍射仪和扫描电子显微镜对其进行表征。随着细菌浓度的增加，已开发的传感器显示出体电阻显着降低。所开发的传感器经过选择性，可重复性和可重复使用性测试，并显示出良好的效果。
