Graphene oxide is the subject of many researches. Due to his extraordinary electrical, optical and chemical properties its use is widespread. One of the areas is also biology, where GO has proven to be a material that can contribute many improvements in biosensors. The research is focused on materials based on graphene oxide, which are used in design and manufacture of biological sensors. Biosensors are very important in medicine, clinical analysis and general health monitoring. Therefore, their properties and capabilities are constantly being researched and improved. In my work, I researched the properties of GO materials and their application in biological sensors. I studied in more detail the research where graphene oxide is used for different types of biosensors, such as biosensor fort the detection of lysozyme, for the detection of cancer cells and the detection of a pathogen. In the work there are also presented operation biological sensors and their most important properties.
