Lab-on-Chip: Testing Anywhere

Monday, July 7, 2008 - 7:00pm

Dr. Arjang Hassibi's research focuses on new approaches to sense, detect, and analyze biological systems using integrated systems and advanced signal processing techniques. His interdisciplinary research group addresses technical challenges at the interface of engineering and biotechnology.

His current research focuses on developing ultra-high throughput, ultra-low cost portable biosensors. These devices will lead to a significant cost-savings, throughput increases, and enable heretofore infeasible biological assays making in the field biological testing a reality.

Despite the development of chips for these systems, there continues to be a need for improved implementations of micro-scale detection and processing systems for further convenience, scaling, and portability. Dr. Hassibi and his students explore embedding active sensing microelectronic substrates in microfluidic devices. This is one of the biggest challenges for functional integration of complex bio-analytical protocols especially for label-free sensing (i.e., capacitive, impedance and charge sensors). The main idea is to use simple electrode materials and geometries but sophisticated electronics to create programmable sensors for fluid volume, speed, and chemical constituents.
