Taiwan sees growth in biochip technology sector

Xu Junjie, director of Bowei BioTech, said the DNA biochip also combines microelectromechanical technology with biological processes. In its approach, unique signals expressed by the polymorphism of DNA are used for security applications. The signals represent unique markers, and any attempts to change the signals would disable the device. By contrast, signals generated by conventional ICs are vulnerable to unwanted changes during the coding and decoding processes.
