Electrochemical sensors for selective analysis of biomolecules got tremendous attention due to their better sensitivity and construction possibility of the portable cost‐effective devices. The individual or simultaneous sensing of ascorbic acid (AA), dopamine (DA), and uric acid (UA) is challenging due to their close electrooxidation and co‐existing. Recent years, substantial progress is made to develop electrode with smart materials to overcome the issue related to simultaneous sensing. This review is comparatively consolidating the work was done in fabrication of electrochemical sensors for the simultaneous sensing of AA, DA and UA. The various modification materials such as graphene, CNTs, conductive polymers and the ionic liquids characteristics are concisely described with their figure of merits. In the end, the critical analysis, future prospects, and challenges in commercialization are described.

修饰电极，用于生物分子的选择性伏安检测。

用于生物分子选择性分析的电化学传感器由于具有更高的灵敏度和便携式成本效益型设备的构造可能性而备受关注。由于抗坏血酸（AA），多巴胺（DA）和尿酸（UA）的紧密电氧化作用和共存，因此单独或同时检测它们具有挑战性。近年来，在开发具有智能材料的电极方面取得了实质性进展，以克服与同时感测有关的问题。这项审查相对巩固了在同时检测AA，DA和UA的电化学传感器的制造中所做的工作。各种改性材料（例如石墨烯，CNT，导电聚合物和离子液体的特性）将通过其优缺点简明扼要地进行描述。最后，批判性分析
