Abstract

A theranostic agent can be used in both photoacoustic imaging (PAI) and photothermal therapy (PTT) applications. The theranostic agent can include a small molecule, organic compound with absorption in the near-infrared (NIR) interrogation window (700-900 nm). The compound can be a biocompatible organic nanoparticle (ONP). The theranostic agent can be effectively used in PAI and PAI-guided PTT applications. The theranostic agent can be administered to a patient to locate a tumor site in the patient using in vivo imaging techniques. Once the tumor site has been determined, the tumor site can be irradiated with near-infrared light to stop or inhibit the growth of the tumor. An exemplary theranostic agent is provided below
