Nanosheet-Based Electrochemical Sensors for Biomedical Applications

Early diagnosis is crucial not only for the treatment of diseases, but also for improving personal life quality. For these reasons, different methods and technologies are being developed for diagnosis of diseases. Sensor technologies have a very important place among these technologies. Electrochemical sensors are widely used in the diagnosis of diseases by biomarker detection due to their advantages such as being cheaper than alternative methods, simple design, sensitive and accurate detection capacity, portable and suitable for point-of-care use. Furthermore, it is perfectly suited to the analysis of pharmaceutical compounds. In recent years, sensitivity and stability of sensors have been increased by modification of sensors with different nano-bio materials. Nanosheets are one of these nanomaterials. This review highlights the structural properties and advantages of different types of nanosheets and their potential as promising tools for biomedical applications in biomarker and drug analysis.
