Scalable and high throughput biosensing platform

A novel multi-channel high performance embedded system capable of high throughput biological analysis is proposed in this paper. Despite other integrated lab-on-chip solutions based on magnetoresistive biochips have already been developed, they lack the scalability and computational resources to cope with new biochip designs featuring more than 1000 sensors. A new configurable acquisition and processing architecture is proposed, combining dedicated coprocessors to perform signal filtering and other computational demanding tasks, with a central processor controlling the whole system. The mapping of the architecture into a Zynq SoC demonstrated its ability to support 8 times more sensors, while ensuring a sampling frequency 1000+ times higher than the previous platforms. Furthermore, the Zynq reconfiguration abilities provide a mechanism to adapt the processing and maximize the biological sensitivity.
