A spin-off from the University of Twente, called Ostendum, developed the first prototype of a biosensor that can detect within minutes if someone is infected with a virus. The company expects to have his version in the market in 2010.

The device consists of two parts: a lab-on-a-chip system, and a detector. The chip contains tiny channels coated with receptors. With the help of a fluidic system is transported to blood or saliva to the canals. Then substances in saliva or blood can bind to receptors on the chip. A laser light is guided through the channels. The phase of this light is altered by any substance bound to the receptors in any of the channels. Such change will be manifested in the pattern of inference, thereby demonstrating the presence of a virus. The method is highly sensitive and may detect the presence of a viral particle.
