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 (3) for mounting a biochip (6) and scanning the biochip (6) in a two-dimensional manner, a controller (4) for the X-Y stage, a magnetic sensor (1) for reading the magnetic field strength, an ohmmeter (2), and a computer (5) 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.
