ABSTRACT
A highly sensitive, selective and stable biosensor is always necessary for quality checking and the healthcare sector. A biosensor consists of a bioreceptor, transducer, analyte and acquisition unit to display. A paper substrate-based 8-hydroxy-2'-deoxyguanosine (8-OHdG) electrochemical biosensor was reported by Martins et al. Recently, black phosphorous attracted considerable attention in the development of highly sensitive and reliable biosensor. Laser-applied graphene used biosensor was reported to detect chloramphenicol. The carbon and metallic nanomaterials-based nanocomposites were also studied for the development of biosensors. The solution-gated graphene transistors are used as a simple and low-cost biosensor for the instantaneous sensing of glucose and uric acid in tears. Another FETs-based biosensor was reported for DNA sensing by utilizing graphene-based solution-gated field effect transistors. The WGM-based biosensors are attractive due to their mesmerizing properties such as small size, high sensitivity, fast response, label-free, and on-time detection.
