Abstract
Infectious diseases have been sources of large-scale epidemics and pandemics resulting in millions of casualties worldwide. Detection of these biological agents normally involves several lab processes including sample preparation, nucleic acid separation and amplification, and diagnostic analysis. These steps, either performed manually or automated by high-throughput machinery, are tedious, expensive, and highly susceptible to cross-contamination. The present system is an integrated lab-on-a-device designed, developed, and tested in compatibility with a mechanical fixture for sample-to-answer biological analysis of infectious diseases.
