Synergistic phototherapy combining photodynamic therapy (PDT) and photothermal therapy (PTT) based on near-infrared (NIR) dyes using a single light source offers the opportunity to treat diseases at deep locations. In this study, we reported human serum albumin (HSA)-involving tetra(butylamino)phthalocyanine (Pc)-based nanomaterials of HSA-α-Pc and HSA-β-Pc as highly efficient dual-phototherapy agents
使用单一光源的基于近红外 (NIR) 染料的光动力疗法 (PDT) 和光热疗法 (PTT) 相结合的协同光疗法提供了治疗深层疾病的机会。在这项研究中,我们报道了人血清白蛋白 (HSA) 涉及的四(丁基氨基)酞菁 (Pc) 基HSA-α-Pc和HSA-β-Pc纳米材料作为高效的双光疗剂,即 1(4) ,8(11),15(18),22(25)-四(丁氨基)酞菁 ( α-Pc ) 和 2(3),9(10),16(17),23(24)-四(丁氨基) ) 酞菁 ( β-Pc )。HSA -α-Pc和HSA-β-Pc在单次 NIR (808 nm) 激光照射下均表现出优异的光热效应1 Pcs的荧光发射猝灭。与HSA-β-Pc相比, HSA-α-Pc表现出更好的单线态氧生成能力,其高效的 PDT/PTT 双光疗法在单次 808 nm 激光照射下的体外和体内实验也得到了很好的证明。总体而言,这种方法对于在单个
