    • Described are methods for detecting a target analyte in a test sample by providing a solid support comprising an electrode comprising: (i) a self-assembled monolayer (SAM), (ii) a covalently attached electroactive active moiety (EAM) comprising a transition metal complex comprising a self-immolative moiety and a peroxide sensitive moiety (PSM), wherein said EAM has a first E 0 ; then contacting the target analyte and said solid support under conditions wherein said target analyte reacts with a peroxide generating enzyme to generate peroxide and said self- immolative moiety is removed such that said EAM has a second E 0 test sample; and then detecting said second E 0 as an indication of the presence of said target analyte. Also provided are compositions for use in the preceding methods.
    • 描述了通过提供包括电极的固体支持物来检测测试样品中的目标分析物的方法,所述固体支持物包括:(i)自组装单层(SAM),(ii)共价连接的电活性活性部分(EAM),其包含过渡金属 复合物,其包含自身残留部分和过氧化物敏感部分(PSM),其中所述EAM具有第一E0; 然后在其中所述目标分析物与产生过氧化物的酶反应产生过氧化物的条件下接触目标分析物和所述固体支持物,并且去除所述自消除部分,使得所述EAM具有第二种E0测试样品; 然后检测所述第二E0作为所述目标分析物的存在的指示。 还提供了用于前述方法的组合物。

    • Compositions and methods for the detection of enzymes using the nuclear reorganization energy, lambda, of an electron transfer process. The method comprises adding a test sample comprising a target enzyme to a solid support comprising an electrode, the electrode comprising a self-assembled monolayer (SAM), a covalently attached eletroactive active moiety (EAM) comprising a transi metal complex with an EO, and a plurality of substrates attached to said electrode, wherein said substrates are substrates of said enzyme. The method further comprises contacting said target enzyme and said substrates to form a plurality of reactants and determining the presence of said enzyme by measuring a change of said EO.
