Towards in the Field Fast Pathogens Detection Using FPGAs

The rapid detection and identification of infectious pathogens are a critical need for healthcare in both developed and developing countries. There is a need for portable diagnostics and epidemiological surveillance systems that can be deployed in remote field settings for infectious diseases testing, such as pandemic "hotspots" in Africa or southeast Asia. Together with the Vital-IT and Swiss-Prot groups, we developed a fast pathogen detection embedded hardware accelerator (no bigger than 75x50mm) capable of analyzing up to 250Mnt/s of DNA sequence. To deploy this solution, an embedded DNA Next Generation Sequencer (NGS) is used for retrieving the genetic material from patient's sample at the point of care (e.g., the Oxford Nanopore Technologies MinION). Successively, the collected DNA sequences are analized in order to detect the presence of known pathogen patterns. Currently, up to 100 different pathogens can be analized at the same time using one single embedded accelerator. Due to the low-power consumption of this hardware accelerator, it is possible to give access to worldwide health organizations and local administrations to a complete real-time embedded and battery powered surveillance solution. Moreover, this solution can greatly scale to big computing clusters, where a larger pathogens number can be analized in parallel, outperforming current state of art computationally expensive solutions.
