Abstract

This article demonstrates how controlled hyperthermia at the cellular level can be achieved.The method is based on the simultaneous intracellular incorporation of fluorescence nanothermometers (CdSe quantum dots) and metallic nanoheaters (gold nanorods).Real-time spectral analysis of the quantum dot emission provides a detailed feedback about the intracellular thermal loading caused by gold nanorods excited at the plasmon frequency. Based on this approach, thermal dosimetry is assessed in such a way that the infrared laser (heating) power required to achieve catastrophic intracellular temperature increments in cancer cells is identified.This pure optical method emerges as a new and promising guide for the development of infrared hyperthermia therapies with minimal invasiveness.
