IEEE Sens J. 2020 Nov 9;21(5):5598-5611. doi: 10.1109/JSEN.2020.3036748. eCollection 2021 Mar 1.


This review paper discusses the properties of nanomaterials, namely graphene, molybdenum disulfide, carbon nanotubes, and quantum dots for unique sensing applications. Based on the specific analyte to be detected and the functionalization techniques that are employed, some noteworthy sensors that have been developed are discussed. Further, biocompatible sensors fabricated from these materials capable of detecting specific chemical compounds are also highlighted for COVID-19 detection purposes, which can aid in efficient and reliable sensing as well as timely diagnosis.

Keywords: COVID-19; Graphene; biocompatible; quantum dots (QDs); sensors.
