Bioengineering of Solution Processed Graphene for the Development of Ultrasensitive Flexible Biosensing Platform

Development of low-cost, flexible and ultrasensitive biosensing platforms for rapid detection of different human metabolites is of great importance for the healthcare, pharmaceuticals and biomedical diagnostics sectors. Synthesis of novel functionalized nanomaterials with high surface area is a key step in the fabrication of high flexible biosensing devices1. Flexible biosensors are one of the most promising next generation wearable self-monitoring devices, as material flexibility is very crucial to attach on a patient’s body part and maintaining the mechanical stability as well as the sensing responses2. In recent years, graphene based materials have invoked a new era for developing smart hybrid material based biosensors. Graphene could offer a perfect solution as an ideal signal transducer for the development of low-cost bioelectronics devices3.
