Abstract
The present invention provides a high-sensitive, inexpensive biochip reader for reading a biochip as compared to a fluorescence method. The biochip reader is provided with an X-Y stage ( ) for mounting a biochip ( ) and scanning the biochip ( ) in a two-dimensional manner, a controller ( ) for the X-Y stage, a magnetic sensor ( ) for reading the magnetic field strength, an ohmmeter ( ), and a computer ( ) for signal processing. As a result, a high-performance, inexpensive biochip reader can be provided without using an expensive laser or an expensive optical system, by employing a magnetic sensor and a disk driving mechanism generally used in a hard disk drive and the like.
