Design of electrochemical sensor for rice DNA detection

The biosensors which based on the electrochemical technique have several advantages than the others; gravimetric and optical technique, etc. Due to its simplicity, user friendly and low cost devices, the semiconductor thin film such an indium oxide doped tin (ITO) was utilized as substrate and associated with specific match between probe ssDNA and complemented target DNA. With those concept and materials, the devices would decrease time consume and budget for rice aromatic gene detection compared to other techniques and also substrates. In additional, this surface successfully distinguishes similar appearance of aromatic and non-aromatic rice seed such as KDML 105 and Phatumthani 1.
