光动力疗法(PDT)是一种临床认可的癌症治疗策略,具有无创性、副作用小、空间分辨率高等特点。然而,激发光的穿透深度严重限制了光动力疗法的发展。在此,我们报道了一种具有聚集诱导发光特性(AIEgen)且活性氧(ROS)生成效率高的高效荧光团TBD,并将其与近红外(NIR)光可激发的上转换纳米粒子(UCNP)相结合,构建了近红外光可激发的UCNP@TBD纳米复合材料。所形成的纳米复合材料具有优异的光稳定性、良好的生物相容性,并且在近红外光激发下,通过福斯特共振能量转移(FRET)能够高效地产生ROS,从而实现近红外光激发的光动力疗法。此外,所提出的近红外光激发光动力疗法能够打破传统光动力疗法中穿透深度与激发体积之间的僵局,有效提高抗癌治疗效果。体外癌细胞消融实验和体内肿瘤生长抑制实验证实,所提出的UCNP@TBD纳米复合材料是一种很有前景的近红外光激发光动力治疗剂,在未来转化研究中具有巨大潜力。 基于具有优异光稳定性、良好生物相容性和高效ROS生成能力的UCNP@AIEgen纳米复合材料,实现了近红外光激发的光动力抗癌治疗。
Photodynamic therapy (PDT), a clinically approved cancer treatment strategy, features non-invasiveness, few side-effects, high spatial resolution, etc. The advancement of PDT has been significantly restricted by the penetration depth of the excitation light. Herein, an effective fluorogen, TBD, with aggregation-induced emission characteristics (AIEgen) and high reactive-oxygen-species (ROS) generation efficiency was reported and integrated with a near infrared (NIR) light excitable upconversion nanoparticle (UCNP) to construct NIR light excitable UCNP@TBD nanocomposites. The formed nanocomposite has excellent photostability, good biocompatibility, and efficient ROS generation under NIR light excitation via Förster resonance energy transfer (FRET), enabling NIR light excited PDT. Moreover, the proposed NIR light excited PDT can break the impasse between the penetration depth and excitation volume in conventional PDT, effectively improving the anticancer therapeutic outcome. In vitro cancer cell ablation and in vivo tumor growth inhibition validated that the proposed UCNP@TBD nanocomposite is a promising NIR light excitable PDT agent with great potential for future translational research.
