Paper Abstract

A novel oligonucleotide chip with porous silicon / oxidized porous silicon (PS/OPS) as its substrate has been developed. The attachment rate and detection sensitivity were improved obviously due to enormous surface area of PS/OPS compared to the existing conventional techniques. No dependence of storage condition on the detection sensitivity is found (signals variation is within SD). Stability of the oligonucleotide chips is good.
