Carbon-based nanomaterials against SARS-CoV-2: Therapeutic and diagnostic applications

“…On the other hand, the great electronic conductivity resulting from the exclusive structures of carbon nanomaterials, such as CNTs, makes them suitable for their use in transducers of sensors, which convert the identification of a target into an electrical signal. Although, a great specific area is promising for immobilizing a high amount concentration of functional units on the surface of the nanomaterial, which identifies the target analytes in the biosensors [44] . In addition, with the recent advances in synthesis assay, characterization/modification techniques, carbon-based nanomaterials can be applied as attractive candidates for different types of scalable technologies, particularly in the inactivation of coronavirus and the development of point-of-care systems [9] .…”

Sugar Molecules Detection via C2N Transistor-Based Sensor: First Principles Modeling

“…These materials are more stable and have better electrical conductivity than pristine carbon. The electrical conductivity of carbon nanomaterials can be improved by nitrogen atoms acting as electron acceptors, increasing their sensitivity for biosensing applications [ 49 ]. Additionally, nitrogen doping can increase the carbon nanostructures’ chemical stability, strengthening their resistance to degradation.…”
