Two dimensional nanosheet materials as sensor become suitable for flexible chemical resistance, exceptional physicochemical, electrical, and mechanical properties. The electrical properties of these nanosheet sensors have been customized via suitable doping, surface modification and manufacture composite materials. Instead of pristine graphene, two dimensional nanosheets; phosphorous-doped, boron-doped or fluorinedoped graphene nanosheet sensors show evidence of better sensing response with either P-type or N-type sensing characteristics. Apart from graphene nanosheet sensors, several metal oxides, transition metal dichalcogenides sensors and composites of metal oxide and metal dichalcogenides also exhibit excellent sensing performance. These sensors are recognized for prompt response-recover behavior, low limit of detection and easy to fabricate on light weight electrode surface. Elucidation of various electrochemical sensor devices improvised the use of several nanosheets as active sensing materials have been discussed in simple and lucid manner in this article through citation of literature examples.
