摘要
The use of potentiometric microsensors is demonstrated here for the first time to detect DNA hybridization. Cadmium sulfide nanocrystal labels bound on a secondary oligonucleolide are dissolved and detected with cadmium-selective microelectrodes exhibiting DNA detection limits of ca. 2 fmol in a 200 mu sample.
