Precisely how the cells behave depends on the kinds of cells placed in the chamber—cancer cells, for example, behave differently than healthy cells—and on what design is printed onto the electronic strip. So for example, one strip design could screen for breast cancer, while another detected AIDS. Technicians wouldn’t necessarily need to create the designs themselves. If the idea takes off, they could just print previously-created designs via an existing template. And because the system is contactless, each electronic strip can be reused. In addition to clinical applications in poor nations, the chip also frees researchers with tighter budgets to experiment.
