OSAKA -- Precision-equipment maker Shimadzu Corp. said Monday it will begin developing a next-generation DNA-mapping device by using nanotechnology.

The Kyoto-based company said it hopes to put the new device on the market by spring 2003.

The speed of the device, to be priced at around 70 million yen, is expected to be more than 10 times faster than existing ones, and its running cost is expected to be less than a tenth of existing models, it said.

The company aims to sell about 50 units in the 2004 business year.
