The electronic response of both pristine and Al-doped BC₃ nanosheets toward 3, 4-dihydroxyphenyl ethylamine, i.e. dopamine (DA) was studied through density functional theory. Based on the adsorption energy the tendency of pristine BC₃ toward DA drug insignificant and also after adsorption of DA drug the electronic properties of BC₃ were changed negligibly. While doping the sheet by Al significantly increases its reactivity and sensitivity toward the DA drug. By adsorption of DA HOMO-LUMO gap dramatically decreased of from 1.34 to 1.12 eV, thereby enhancing the electrical conductivity. It indicates that the doped BC₃ nanosheets may be a suitable candidate as a DA electronic sensor, unlike the pristine BC₃. Furthermore, the work function of doped BC₃ was changed significantly after DA adsorption. Based on these results the doped BC₃ can also act as a work function-type sensor to the sensing of DA was used. Finally, the most important factor of the doped BC₃ sheet is a short recovery time of 7.36 ms for the desorption process of DA.

通过密度泛函理论研究了原始的和Al掺杂的BC ₃纳米片对3,4-二羟基苯基乙胺即多巴胺（DA）的电子响应。基于吸附能量，原始BC ₃向DA药物的趋势微不足道，并且在DA药物吸附后，BC ₃的电子性质变化可忽略不计。当用Al掺杂薄板时，显着增加了其对DA药物的反应性和敏感性。通过吸附DA HOMO-LUMO，间隙从1.34 eV急剧降低至1.12 eV，从而提高了电导率。这表明，与原始BC ₃不同，掺杂的BC ₃纳米片可能是适合用作DA电子传感器的候选材料。。此外，DA吸附后，掺杂的BC ₃的功函数发生了显着变化。基于这些结果，掺杂的BC ₃还可作为功函数型传感器来检测DA。最后，掺杂的BC ₃片的最重要因素是DA解吸过程的7.36 ms的短恢复时间。
