Abstract :
A novel cDNA array sensor with porous silicon/oxidized porous silicon (PS/OPS) as its substrate has been developed. The binding capacity, linear dynamic range, and detection limit of the sensor were improved due to enormous specific surface area of PS/OPS compared to the existing conventional techniques. The cDNA array sensor shows good stability as the sensor can bear 80 centre degree of temperature, 75% of relative humidity and 3.6 kLx of irradiation (signal changes are close to SD), respectively
