The company's principal activity is to develop lab-on-a-chip technologies and to manufacture labchip systems. the company's labchip systems are based on distinct chip formats namely personal laboratory systems, high throughput systems and application development system. each chip contains a network of microscopic channels through which fluids and chemicals are moved, using electricity or pressure, in order to perform experiments. these chips are the key components of the labchip systems, which also include reagents as well as instruments and software. the labchip systems miniaturize, integrate and automate many laboratory processes and put them on a chip that can fit in the palm of a child's hand. the company also offers screening services under its value added screening collaboration program to pharmaceutical and biotechnology customers. license fees and contract revenue accounted for 57% of 2001 revenues and product revenue, 43%.
