摘要

Abstract > A sensitive and selective amperometric H <sub>2</sub> O <sub>2</sub> biosensor was obtained by utilizing the electrodeposition of Pt flowers on iron oxide‐reduced graphene oxide (Fe <sub>3</sub> O <sub>4</sub> /rGO) nanocomposite modified glassy carbon electrode (GCE). The morphology of Fe <sub>3</sub> O <sub>4</sub> /rGO and Pt/Fe <sub>3</sub> O <sub>4</sub> /rGO was characterized by transmission electron microscopy (TEM) and scanning electron microscopy (SEM), respectively. The step‐wise modification and the electrochemical characteristics of the resulting biosensor were characterized by cyclic voltammetry (CV) and chronoamperometry methods. Thanks to the fast electron transfer at the Pt/Fe <sub>3</sub> O <sub>4</sub> /rGO electrode interface, the developed biosensor exhibits a fast and linear amperometric response upon H <sub>2</sub> O <sub>2</sub> . The linear range of Pt/Fe <sub>3</sub> O <sub>4</sub> /rGO is 0.1～2.4 mM (R 2 =0.998), with a sensitivity of 6.875?μA/mM and a detection limit of 1.58?μM (S/N=3). In addition, the prepared biosensor also provides good anti‐interferent ability and long‐term stability due to the favorable biocompatibility of the electrode interface. The proposed sensor will become a reliable and effective tool for monitoring and sensing the H <sub>2</sub> O <sub>2</sub> in complicate environment. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><Abstract XMLNS =“http://www.wiley.com/namespaces/wiley”type =“main”xml：lang =“en”> <标题类型=“main”>抽象</ title> >敏感通过利用Pt花的电沉积在氧化铁 - 还原的氧化铁上（Fe <sub> 3 </ sub> o <sablo> o <shib>亚> 4 </ sub> / rgo）纳米复合材料改性玻碳电极（GCE）。 Fe <sub> 3 </ sub> O <sub> 4 </ sub> / rgo和pt / fe <sub> 3 </ sub> o <sub> 4 </ sub> / rgo的形态表征电子显微镜（TEM）和扫描电子显微镜（SEM）。通过循环伏安法（CV）和计时法的方法表征了所得生物传感器的逐步改性和电化学特性。由于PT / FE <sub> 3 </ sub> O <sub> 4 </ sub> / rgo电极接口的快速电子传递，开发的生物传感器在H <sub> 2 <sabl> 2 < / sub> O <sub> 2 </ sub>。 Pt / Fe <sub> 3 </ sub> O <sub> 4 </ sub> / rgo的线性范围为0.1〜2.4 mm（R 2 </ sup> = 0.998），灵敏度为6.875 ？μA/ mm和1.58Ωμm的检测限μm（s / n = 3）。此外，由于电极界面的有利生物相容性，所制备的生物传感器还提供良好的抗干扰能力和长期稳定性。该提出的传感器将成为可靠且有效的工具，用于监视和感测到复杂环境中的H <SUB> 2 </ sub> O <sub> 2 </ sub>。 </ p> </ abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-22546/'>《Electroanalysis》</a> <b style="margin: 0 2px;">|</b><span>2017年第6期</span><b style="margin: 0 2px;">|</b><span>共6页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Zhao Xueling&option=202" target="_blank" rel="nofollow">Zhao Xueling;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Li Zhanhong&option=202" target="_blank" rel="nofollow">Li Zhanhong;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Chen Cheng&option=202" target="_blank" rel="nofollow">Chen Cheng;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Wu Yihua&option=202" target="_blank" rel="nofollow">Wu Yihua;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Zhu Zhigang&option=202" target="_blank" rel="nofollow">Zhu Zhigang;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Zhao Hongli&option=202" target="_blank" rel="nofollow">Zhao Hongli;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Lan Minbo&option=202" target="_blank" rel="nofollow">Lan Minbo;</a> </p> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zkzz" style="display: none;">展开▼</span> </div> </li> <li> <div style="display: flex;"> <span class="lefttit">作者单位</span> <div style="position: relative;margin-left: 3px;max-width: 639px;"> <div class="threelineshidden zhankaihshouqi" id="fOrgthree"> <p>School of Environmental and Materials EngineeringShanghai Polytechnic UniversityShanghai 201209 P.
