AIMS: A carbon-wrapped nanoscaled thermometer for a contactless temperature control in biological systems on the cellular level is presented. MATERIALS & METHODS: The thermometer is based on multiwalled carbon nanotubes (MWCNTs) filled with materials with strongly temperature-dependent nuclear magnetic resonance (NMR) parameters. The NMR frequency shift and relaxation time were measured in cuprous-iodide-filled CNTs at different temperatures. RESULTS: The experimental data indicate a pronounced temperature dependence of the NMR parameters, thereby realizing the nanoscaled thermometer. CONCLUSION: This study is a proof-of-concept that the functionalized CNTs can be used as a contactless thermometer in biomedical applications.
