Description

Our newly developed active paper-based open chips, fabricated by inkjet printing, and their application in lab automation will be presented. This technology simplifies the workflow and improves reaction accuracy compared to conventional methods, which often require multiple pre-treatments, mixing, separation, and thermal treatment on a single paper chip design.[1-3] We will discuss the fabrication process of these chips and showcase examples of biosensors and point-of-care applications. Our paper devices can serve as an alternative tool for disease detection in developing countries, where cost-effective and accessible diagnostics are urgently needed.
