The near-infrared (NIR) window refers to a range of wavelengths (700–1300 nm) in which biological tissues are highly transparent.[1] Consequently, biological imaging and therapy modalities employ light at these wavelengths for the monitoring[1] and triggering[2] of biological events in vitro and in vivo. For instance, photothermal ablation takes advantage of NIR absorbing materials for transducing light into heat.[2] The resultant thermal energy can be used for a number of applications, such as tissue ablation and drug release. Despite the intense interest in NIR photothermal agents, their development has suffered from considerable challenges. In particular, few nanomaterials display the requisite absorption profiles required for NIR photothermal transduction.
