We present a preliminary <i>in vivo</i> study of fluorescence imaging and photothermal therapy (PTT) of human oesophageal adenocarcinoma using multi-functionalised gold nanorods (GNRs). After establishing tumour xenograft in mouse functionalised GNRs were administrated intravenously (IV). Fluorescence imaging was performed to detect the tumour area. The intensity of the fluorescence signal varied significantly across the tumour site and surrounding tissues. PTT was then performed using a 808 nm continuous wave diode laser to irradiate the tumour for 3 minutes, inducing a temperature rise of ~44°C, which photothermally ablated the tumour.
