Abstract: combination of cancer therapy (hyperthermia with other therapies) holds tremendous
potential for therapeutic improvement. Conventional methods of inducing hyperthermia
are incapable of limiting a high-temperature increase at the tumor location while also
preserving unexposed healthy tissues. Different materials available are not suitable for the
combined application of hyperthermia and photothermal therapy (PTT). The use of carbonbased
nanomaterials for cancer therapy has increased rapidly due to their ability to transport
various anticancer drugs and to function as a photothermal agent. In this regard, the graphene
family of 2D carbon nanomaterial graphene oxide (GO) and reduced graphene oxide (rGO)
has emerged as a promising candidate for cancer PTT due to its excellent photothermal conversion
in the near-infrared range, large specific surface area for drug loading, and scope for
functionalization with functional groups/ molecules such as photosensitizers, siRNA, ligands, and so on with no
cumulative toxicity. The availability of functional groups such as hydroxyls, epoxides, and carbonyls on GO
groups, renders flexible modification leading to biocompatibility, facilitating it for an ideal drug delivery vector. In
the present review, recent advances in combinational PTT providing synergistic benefits of multiple modalities are
discussed.
