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
治疗剂可用于光声成像(PAI)和光热治疗(P
TT)。治疗剂可包括在近红外(NIR)询问窗口(700-900 纳米)具有吸收功能的小分子有机化合物。该化合物可以是
生物相容性有机纳米粒子(ONP)。治疗剂可有效用于 PAI 和 PAI 引导的 P
TT 应用。可向患者施用治疗剂,利用体内成像技术定位患者的肿瘤部位。一旦确定肿瘤部位,就可以用近红外光照射肿瘤部位,阻止或抑制肿瘤生长。下文提供了一种示例性治疗剂
