What do wheelchair manufacturing, cancer research, chemical sensors, air pumps and materials for electron microscopes have in common?

They're all done in team with University of Washington researchers, and get grant money from the state. The Washington Technology Center gave half a million dollars to five companies engaged in these diverse realms, at the rate of about $100,000 each.

The funding is expected to generate some 200 jobs in Washington, the center said in a statement Tuesday.

The grant winners are:

- Artemisia BioMedical Inc, of Newcastle, which seeks to develop therapies for cancer and other diseases
- dTEC Systems, a developer of environmental monitoring systems, to create low-cost chemical sensor technology
- Kronos Air Technologies, with operations in Redmond, to make an energy-efficient electrostatic air pump.
- Hummingbird Scientific, of Lacey, to make a high-temperature heating element for use in the transmission electron microscope.
- MagicWheels Inc., of Seattle, to test a wheel manufacturing process for its wheelchairs.
