Development of theranostic agent for imaging-guided photothermal therapy has been of great interest in the field of nanomedicine.In this work,our synthesized near-infiared (NIR) dye,IR825,is bound with human serum albumin (HSA),forming a HSA-IR825 complex with greatly enhanced fluorescence under 600 nm excitation by as much as 100 folds compared to that of free IR825,together with a rather high absorhance at 808 nm.The unique optical behavior of HSA-IR825 enables imaging and photothermal therapy at separated wavelengths both with optimized performances.As revealed by in vivo fluorescence imaging,HSA-IR825 upon intravenous injection shows high tumor uptake together with low levels of retentions in other organs.While HSA is an abundant protein in human serum,IR825 is able to be excreted by renal excretion as evidenced by high-performance liquid chromatography (HPLC) [1].

为了节水,山西某电厂拟将2×350MW机组循环冷却水系统的补充水由部分软化水更改为全量软化水。本文需要围绕阻垢缓蚀剂开展以全量软水为补充水的循环冷却水质控制技术的研究,本研究主要结果如下:(1)2011～2016年的水质统计资料表明,该电厂循环冷却水的Cl-含量较高,浓缩倍数维持在3.0左右,且软水率逐年提高。综合考虑节水目标、原水水质及软水水质,建议循环冷却水的浓缩倍数控制在5～6,补充水采用全
