Here we report an easy method to characterize the high sensitivity of MWCNTs to nIR-laser irradiation.
MWCNTs respond to nIR-lase irradiation in reducing transiently their electrical resistance.
An increase of temperature of MWCNTs is observed during nIR-laser irradiation.
We provide experimental evidence for the uses of MWCNTs in laser hyperthermia for cancer treatment.
