摘要：

近年來，含氮類藥物已成為許多重要疾病的治療首選。因此，對(duì)含氮類藥物的分析研究變得越來越重要。在本文中，我們介紹了一種基于納米材料的電化學(xué)和電化學(xué)發(fā)光傳感器，用于含氮類藥物的分析研究。我們使用碳納米管、量子點(diǎn)和金納米粒子作為納米材料，利用它們的獨(dú)特電學(xué)和光學(xué)性質(zhì)，構(gòu)建了一系列傳感器，包括電化學(xué)傳感器和電化學(xué)發(fā)光傳感器。為了實(shí)現(xiàn)高靈敏度和選擇性，我們還通過改變傳感器表面的功能化修飾，在傳感器表面引入一些具有親和性的配體，如環(huán)糊精和離子液體。

我們選擇了一些常用的含氮類藥物，如甲氧芐啶、氨基胍和磺唑嘧啶作為目標(biāo)分析物。我們利用這些傳感器，成功地開發(fā)了一種新的含氮類藥物的分析方法。在優(yōu)化傳感器的工作條件后，我們獲得了較佳的線性范圍、檢測(cè)限和穩(wěn)定性。同時(shí)，我們還進(jìn)行了一些實(shí)際樣品的檢測(cè)，結(jié)果顯示，我們的方法具有很好的重現(xiàn)性和準(zhǔn)確性。這些結(jié)果證明，我們所開發(fā)的傳感器可用于含氮類藥物分析的實(shí)際應(yīng)用。

本文的研究結(jié)果表明，納米材料在電化學(xué)和電化學(xué)發(fā)光傳感器中的應(yīng)用，可以大大提高傳感器的靈敏度和選擇性，同時(shí)對(duì)于含氮類藥物等目標(biāo)分析物的檢測(cè)具有重要的研究?jī)r(jià)值。
