Two-Dimensional Materials-Based Plasmonic Sensors for Health Monitoring Systems—A Review

Two-dimensional materials-based plasmonic sensors are widely used in many sensing applications, particularly in biosensors due to their distinctive qualities such as label-free detection, cost-effective, and real-time monitoring. This article summarizes the advances in the 2-D materials-based plasmonic sensors with respect to different materials such as graphene, antimonene, phosphorene, blue phosphorous, molybdenum sulfide, molybdenum selenide, and tungsten selenide. This review also includes the comparison based on the sensitivity, detection range, and detection limit of the 2-D materials-based plasmonic sensors in context to those biosensing applications. These parameters in true sense determine the sensor’s accuracy and applicability in health monitoring systems for desired results.
