对吡咯-链霉亲和生物芯片上的小分子的检测
We demonstrate here that the SPRi technology developed by Genoptics is thoroughly suited to detect small molecules, such as biotin, with molecular weights below 500 Da. Biotin captured on pyrrole-streptavidine spots and electro-grafted on SPRi-Biochip is specific and shows the high sensitivity of our SPRi technology instruments.
