Water‐gated organic field‐effect transistors (WGOFETs) are expected to have a strong impact in the field of electronic biosensors owing to the synergism between the transduction function of the transistors with the fact that they can be operated in physiological media. Nonetheless, a limited library of gate electrodes has currently been explored for this aim. Herein, different polymer nanocomposite carbon paste gate electrodes (NC‐CPgEs) are successfully exploited for the first time as unusual nonmetal gate electrodes in WGOFET devices employing four types of carbon nanoallotropes with dimensionality ranging from 0D to 3D (i.e., carbon nanohorns, carbon nanotubes, reduced graphene oxide, and graphite, respectively). Interestingly, after an accurate electrochemical and electrical characterization, it is demonstrated that the WGOFETs with the developed NC‐CPgEs reveal excellent behaviors comparable to that achieved with conventional gate electrodes, such as gold or glassy carbon electrodes. Further, depending on the carbon nature the device performance can be tuned, being the devices based on reduced graphene oxide the ones showing a better electrical response. Accordingly, this work can pave the way for widespread applications of NC‐CPgEs for the development of a new generation of WGOFET devices based on carbon nanostructures.

水栅有机场效应晶体管中新型栅电极从0D到3D的高分子碳糊纳米节电器的电子性能

水闸式有机场效应晶体管（WGOFET）有望在电子生物传感器领域产生巨大影响，这是由于晶体管的转导功能之间的协同作用，因为它们可以在生理介质中工作。尽管如此，目前已经为此目的开发了有限的栅电极库。在本文中，不同的聚合物纳米复合碳糊栅电极（NC-CPgEs）首次成功地作为WGOFET器件中的非常规非金属栅电极，采用了尺寸从0D到3D的四种类型的碳纳米节肢（即碳纳米角，碳纳米管） ，分别还原的氧化石墨烯和石墨）。有趣的是，经过准确的电化学和电学表征后，事实证明，具有开发的NC-CPgE的WGOFET具有出色的性能，可与传统的栅电极（如金或玻璃碳电极）相比。此外，取决于碳的性质，可以调节器件性能，作为基于还原的氧化石墨烯的器件，其表现出更好的电响应。因此，这项工作可为NC-CPgE的广泛应用铺平道路，以开发基于碳纳米结构的新一代WGOFET器件。
