Water-dispersible and red emissive carbon dots can simultaneously generate 1O2 and heat (symbolized by the flame around the carbon dots) under 635 nm laser irradiation. As described by Y. Gu, P. Wang, and co-workers on page 665, this unique property enables C-dots to act as red light-triggered theranostic agents for imaging-guided photodynamic-photothermal therapy in vivo.
