Abstract

Today, the smart sensing platforms concept has been programmable with multiplexed desired target emitters with the emergence of ultra-sensitive diagnosis on nanochip, lab-on-a-chips, and three-dimensional printed devices supporting decision-making with artificial-intelligence. Since carbon nanomaterials such as carbon nanotubes, carbon dots, carbon nanofibers, graphene, and carbon nitride etc., have unique properties such as high selectivity, specificity, and sensitivity, biocompatibility and sustainability, low or non-toxicity, ideal recognition and binding affinity, user-friendliness, variety, ease of preparation or use, and easy tunability, scalability, and modification compared to other nanomaterials, aptasensors decorated with carbon nanomaterials are being considered to monitor and audit food safety and quality control, environmental, bio/nanotechnology, and medicine to detect various targets like biomarkers, heavy metals, antibiotics, pesticides, allergens, and other contaminants. This review paper comprehensively and specifically investigates the characteristics, synthesis, and immobilization of aptasensors based on carbon nanomaterials. The use and integrity of carbon nanomaterials-functionalized aptasensors on portable and electronic devices (microfluidic chip/smartphone) for the tracking and analysis of different hazardous materials, targets, and biomarkers are also covered in this paper. Finally, it addresses how carbon nanomaterials -functionalized aptasensors may be used to monitor and identify targets in the environment and food chain. Therefore, commercialization and industrialization of carbon nanomaterials -functionalized aptasensors as “Lab-on-chip” systems facilitate the tracking and monitoring of hazardous materials/contaminants and various targets in the food chain and environment for consumers and beneficiaries using portable smart electronic tools. Nevertheless, to overcome possible limitations in the construction and introduction of multifunctional carbon nanomaterials -functionalized aptasensors with the capability to use in complex matrices as rapid, portable, and user-friendly, as well as disposable, online/offline and integrated sensors to detect and monitor hazardous material/targets is necessary, which has been highlighted in this study. © 2025 Elsevier B.V., All rights reserved.
