Abstract
In this communication, a new photoelectrochemical aptasensor with Au nanoparticle functionalized self-doped TiO2 nanotube arrays (Au/SD-TiO2 NTs) as the core sensing unit and aptamers as the recognition unit was set up to accomplish the sensitive and selective detection of kanamycin with the lowest detection limit of 0.1 nM.
摘要
在本通讯中，构建了一种新型光电化学适体传感器，该传感器以金纳米颗粒功能化的自掺杂二氧化钛纳米管阵列（Au/SD-TiO2 NTs）作为核心传感单元，以适体作为识别单元，实现了对卡那霉素的灵敏且选择性检测，最低检测限为0.1 nM。
