Single‐walled carbon nanotubes coated with gold nanoparticles (Au NPs) have been prepared by using a thiol‐functionalized ionic liquid (IL) as a type of glue. The resulting material has an ideal absorption and heating profile for a photothermic converter. Furthermore, they are biocompatible and selectively enter lysosomes in tumor cells because of the enhanced permeability and retention (EPR) effect, in which the structural changes in tumor tissue allows macromolecules to enter and accumulate. Due to an enhanced near‐infrared (NIR) absorption, irradiation with a NIR laser is effectively transferred into heat to cause localized hyperthermia, resulting in rapid cell death.
