These days, sensors are widely used in a variety of underwater sites like marine monitoring, fish-farming and water quality monitoring. However, to achieve reliable sensor data from long-term monitoring in aqueous solution, several challenges still need to be solved. Biofilm formation both on sensor housings and membranes is among one of the most serious challenges, which strongly influences the sensor responds and the validity of the results. To prevent biofilm growth, a series of graphene oxide (GO)/silver nanoparticles (Ag NPs) nanocomposites (GOA) have been developed and coated on sensor housing materials, e.g. polypropylene. The antifouling property of the GOA nanocomposite has been demonstrated by antifouling tests using Halomonas. Pacifica (Baumann et al.) Dobson and Franzmann (ATCC® 27122) (H. Pacifica) and a mixture of marine algae. The antifouling property of GOA composites has been proved to be closely related to the dispersibility of Ag NP. The overall work might provide valuable insight into developing antifouling materials for sensors in general.

如今，传感器已广泛用于各种水下场所，例如海洋监测，鱼类养殖和水质监测。然而，要从水溶液中的长期监测中获得可靠的传感器数据，仍然需要解决几个挑战。传感器外壳和膜上的生物膜形成是最严峻的挑战之一，它严重影响传感器的响应和结果的有效性。为了防止生物膜的生长，已经开发出一系列氧化石墨烯（GO）/银纳米颗粒（Ag NPs）纳米复合材料（GOA）并涂在传感器外壳材料上，例如聚丙烯。GOA纳米复合材料的防污性能已通过使用Halomonas的防污测试得到证明。Pacifica（Baumann等人）Dobson和Franzmann（ATCC®27122）（H.Pacifica）和海藻的混合物。事实证明，GOA复合材料的防污性能与Ag NP的分散性密切相关。总体上，这项工作可能会为开发传感器防污材料提供有价值的见解。
