这项工作描述了一个简单的，通用的，廉价的程序来制备光学透明的碳电极，使用蛋白质作为前体。在吸附后，蛋白质涂覆的基底在还原条件（5%H2）下热解以形成超薄导电电极。由于蛋白质自发吸附到界面形成均匀的层，所提出的方法不需要精确控制的制备条件，专门的仪器，或昂贵的前体。所得电极的特征在于电化学，光学和光谱手段的组合。作为概念验证，光学透明电极也被用作开发电化学葡萄糖生物传感器的基底。拟议的薄膜代表了一种方便的替代更复杂，更难获得的碳基纳米材料。此外，这些膜可以在各种基底上形成，而没有尺寸或形状的经典限制。
This work describes a simple, versatile, and inexpensive procedure to prepare optically transparent carbon electrodes, using proteins as precursors. Upon adsorption, the protein-coated substrates were pyrolyzed under reductive conditions (5% H2) to form ultra-thin, conductive electrodes. Because proteins spontaneously adsorb to interfaces forming uniform layers, the proposed method does not require a precise control of the preparation conditions, specialized instrumentation, or expensive precursors. The resulting electrodes were characterized by a combination of electrochemical, optical, and spectroscopic means. As a proof-of-concept, the optically-transparent electrodes were also used as substrate for the development of an electrochemical glucose biosensor. The proposed films represent a convenient alternative to more sophisticated, and less available, carbon-based nanomaterials. Furthermore, these films could be formed on a variety of substrates, without classical limitations of size or shape.
