A spatially addressable bead-based biosensor for simple and rapid DNA detection.

Biosensors & bioelectronics - 18 Jan 2008

Ng Johnson K, Selamat Ezrein S, Liu Wen-Tso

Abstract excerpt

A simple glass-polymer-based biosensor that allows arrays of beads to be immobilized, separated and identified without any prior encoding is developed. To do so, distinct bead types that are conjugated with different oligonucleotide probes are sequentially spotted onto a polymeric matrix (or gel pad) on the surface of the device. The spotted beads are firmly immobilized to the gel pad, acquiring spatial codes...
