Abstract: Fast and inexpensive virus identification protocols are of paramount value to
hinder the increase of pandemic diseases, minimize economic and social damages, and
expedite proper clinical rehabilitation. Until now, various biosensors have been developed
for the identification of pathogenic particles. But, they offer many limitations. Nanotechnology
overcomes these difficulties and allows a direct identification of pathogenic species
in real-time. Among them, nanomaterial based-colorimetric sensing approach for
identifying pathogenic viruses by the naked eye has attracted much awareness because of
their simplicity, speed, and low cost. In this review, the latest tendencies and advancements
used in detecting pathogenic viruses using colorimetric concepts, are overviewed.
We focus on and reconsider the use of distinctive nanomaterials such as metal nanoparticles,
carbon nanotubes, graphene oxide, and conducting polymer for the formation of colorimetric
pathogenic virus sensors.
