8.1 Introduction

Nanomaterials, particularly nanocarbon allotropes, provide numerous advantages for designing new and high‐performance sensing platforms with high sensitivity, rapid response, and fast recovery for multianalyte detection due to their outstanding structures, remarkable properties, low‐cost, and scalable production [1–5]. Sensors based on carbon nanomaterials including carbon nanoparticles (NPs), carbon nanotubes (CNTs), carbon nanodots (CNDs), and graphene derivatives have been extensively used for different sensing applications such as gas/vapor sensing, optical sensing, and electromechanical sensing. Based on these sensing materials, research efforts are largely focused on the exploration of new detection concepts and improvement of sensor performances in terms of sensitivity, selectivity, detection limit, response time, and reversibility. Their practical application is also broad ranging from environmental monitoring, public safety, food ...
