邻苯二甲酸酯(PAEs)是生产中常用的增塑剂,广泛应用于食品包装,玩具,化妆品,洗涤剂等生活中的常见产品,但它对人体健康有严重危害,并会导致男性生殖障碍[1]。
A simple and a controlled partial pyrolysis strategy for fabrication magnetic NiCo/Fe3O4-MOF-74 by using trimetallic NiCoFe-MOF-74 as precursor was demonstrated.
精神活性物质是一类作用于人类中枢神经系统并具较强成瘾性的化合物[1],被认为是一种新型污染物。因其具有较强的生物活性和极性、不易挥发且难以被生物降解,进入水环境后能够持久存在而威胁着生态环境安全。
液体阴极辉光放电微等离子应用光谱检测具有可在大气压下运行,功率低,体积小等特点.本研究通过先后将氢化物发生、光化学蒸气发生技术作为液体阴极辉光放电的样品引入系统,分别实现了对于Sn(Ⅳ,Ge(Ⅳ),Se(Ⅳ),As(Ⅲ),Pb(Ⅱ)以及Hg(Ⅱ)的高灵敏检测,检出限可至0.8,0.5,0.2,0.3和0.17 μg·L-1,同时能够实现对溶液中的As,Se和Hg元素进行价态分析[1-4].
金属离子作为人体内的一种微量元素在人体内发挥着极其重要的作用,因此实时监控生物体内金属离子浓度的变化和分布情况具有非常重要的意义[1].DNA 酶可以特异性识别不同靶标之间极微小的差异,为构建各种分析对象的荧光探针提供了分子识别工具[2].
Many different DNA walker designs have previously been presented in the literature.These demonstrations have included walkers driven by strand exchange reactions[1],DNAzyme-mediated DNA hydrolysis[2],
A label free and tetrahedron DNA nanostructure(3D-DNA)coupling with hybridization chain reaction(HCR)amplification strategy was developed for carinoembryonic antigen(CEA)detection.
An effective and simple homogeneous electrochemical sensing platform for the label-free detection of prostate specific antigen(PSA)based on Cu-MOF non-covalently interplaying with the peptide.
