采用模板合成和可控化学腐蚀相结合的方法制备了直径为100 nm、长度为300 nm的金纳米线组成的三维金刷纳米电极系综（BNEE）。通过扫描电子显微镜（SEM）和透射电子显微镜（TEM）对BNEE的结构和形态进行了成像。当以不同的氧化还原物种表征时，BNEE的真实的活性区域被发现是不同的。柔红霉素（DNR）在金BNEE上的直接氧化还原具有吸收控制的特征和高电流活性。BNEE是检测DNR的可靠和有效的方法。
3D gold brush nanoelectrode ensembles (BNEEs) consisted of gold nanowires 100 nm in diameter and 300 nm in length were fabricated by combining the technologies of template synthesis and controlled chemical etching of the membrane. The structure and morphology of the BNEEs was imaged by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The real active areas of BNEEs were found to be different when characterized by different redox species. The direct redox of daunorubicin (DNR) at the gold BNEEs exhibited absorption-control led characteristics and high current activity. BNEEs are reliable and effective in DNR detection.
