Research output: Contribution to journalArticlepeer-review


A low-cost microfluidic chip has been developed for glucose sensing applications based on the refractive (RI) index changes provided by glucose samples. The sensor chip was developed on a compact disc (CD) substrate by constructing a microfluidic flow-cell on top of it. The chip consists of a microfluidic channel for the transport of liquid samples under observation on the CD substrate. The proposed sensor chip used commercially available CD pieces as transducing element making it very cost-effective and quick sample preparation. The developed sensor chip has high sensitivity, ideally suited for low-cost sensing and quality control applications.
