Photothermal Therapy

Photothermal therapy (PTT) is an emerging therapeutic modalitybased on the generation of a far-infrared wave by an optically excitedmaterial. Withthe development of photo- thermic (PT) agents, such as conjugated organic groups, carbonnanotubes, andmetal-based nanocrystals, PTT has been widely used for tumor imaging and treatment.The NIR laser source was equipped with a 4 mmdiameter laser module with an adjustable power. The photothermal conversionefficiency, η, is calculated using Equation (3) described by Roper

where h is the heat transfer coefficient,S is the surface area of the container, T_max is the equilibriumtemperature, T_Surr is the ambient temperature of the surroundings, Q_Disis the heat dissipation from the light absorbed by the quartz sample cell, I isthe incident laser power (0.8 W cm⁻²), and A is the absorbance ofthe MoTe2-PEG-cRGD nanosheets at 808 nm
