“…Therefore, endless efforts are being made to assemble chemical sensors that could resolve most of the reported issues. [17][18][19][20] To improve the sensitivity and selectivity of graphene-based chemical sensors, researchers have engineered their outcomes by employing various approaches including controlled synthesis of graphene, integration of nanomaterials with graphene and device designs to offer the efficient response of sensors for a wide range of chemical analytes. 10,11 Here, we report a highly facile and cost-effective strategy to fabricate the graphene-based chemical sensor for VOC analytes.…”
