Three-dimensional (3D) printing has proven to be a versatile and useful technology for specialized applications in industry and also for scientific research. We demonstrate its potential use toward the electrochemical detection of nitroaromatic compounds 2,4,6-trinitrotoluene (TNT), 2,4-dinitrotoluene (DNT), and fenitrothion (FT). The detection of these compounds is of utmost importance in military and forensic applications. Stainless steel electrodes were fabricated by 3D printing, and the surface was electroplated with gold. The electrochemical performance of the 3D printed electrodes was compared to that of the conventionally employed glassy carbon electrode (GCE) and proved to be more sensitive toward the detection of all three nitroaromatic compounds. 3D printing of customizable electrodes provides a viable alternative to traditional electrodes for the analysis of samples with electrochemical methods.

用于检测硝基芳香族炸药和神经毒剂的3D打印电极

事实证明，三维（3D）打印是一种通用且有用的技术，适用于工业领域的特殊应用以及科学研究。我们证明了其在硝基芳族化合物2,4,6-三硝基甲苯（TNT），2,4-二硝基甲苯（DNT）和杀nitro硫酮（FT）的电化学检测中的潜在用途。这些化合物的检测在军事和法医应用中至关重要。不锈钢电极通过3D打印制成，表面镀有金。将3D打印电极的电化学性能与常规使用的玻璃碳电极（GCE）的电化学性能进行了比较，并证明对所有三种硝基芳族化合物的检测都更加敏感。
