The Front Cover shows how nano‐graphene oxide can be used as a label for the detection of biomolecules, whereby the electrochemical signal is intrinsic from the graphene material, on which electroactive oxygen functionalities can be reduced, and the reduction extent can be correlated to the presence of the specific analyte. By monitoring the graphene reduction signal after each step of the biosensing, precise quantification of the analyte under investigation can be achieved. More information can be found in the Minireview by A. Bonanni.

前盖显示了如何将纳米氧化石墨烯用作检测生物分子的标记，从而从石墨烯材料获得内在的电化学信号，在其上可以还原电活性氧功能，并且还原程度可以与特定分析物的存在。通过在生物传感的每个步骤之后监视石墨烯还原信号，可以对研究中的分析物进行精确定量。更多信息可以在A. Bonanni的Minireview中找到。
