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, namely 1(4),8(11),15(18),22(25)-tetra(butylamino)phthalocyanine (α-Pc) and 2(3),9(10),16(17),23(24)-tetra(butylamino)phthalocyanine (β-Pc). Both HSA-α-Pc and HSA-β-Pc showed excellent photothermal effects under a single NIR (808 nm) laser irradiation due to the fluorescence emission quenching of Pcs. Compared to HSA-β-Pc, HSA-α-Pc exhibited better singlet oxygen generation ability and its highly efficient PDT/PTT dual-phototherapy was also well evidenced and experiments under a single 808 nm laser irradiation. Overall, this approach would be viable for the fabrication of more new Pc-based metal-free nano agents for PDT/PTT synergistic phototherapy upon a single NIR light source.
基于近红外(NIR)染料并使用单一光源的光动力疗法(PDT)和光热疗法(PTT)相结合的协同光疗为治疗深部疾病提供了机会。在本研究中,我们报道了含人血清白蛋白(HSA)的基于四(丁基氨基)酞菁(Pc)的纳米材料HSA-α-Pc和HSA-β-Pc,即1(4),8(11),15(18),22(25)-四(丁基氨基)酞菁(α-Pc)和2(3),9(10),16(17),23(24)-四(丁基氨基)酞菁(β-Pc),作为高效的双光疗剂。由于酞菁的荧光发射猝灭,HSA-α-Pc和HSA-β-Pc在单一近红外(808 nm)激光照射下均表现出优异的光热效应。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双光疗在单一808 nm激光照射下的实验中也得到了充分证明。总体而言,这种方法对于制备更多基于Pc的无金属纳米剂用于单一近红外光源下的PDT/PTT协同光疗是可行的。
