Ongoing work in the laboratory of Professor Chris Backhouse is aimed at developing a portable and inexpensive lab on a chip instrument. A system capable of molecular biology protocols including sample preparation (SP), polymerase chain reaction (PCR), and melting curve analysis (MCA) would meet the requirements for point of care genetic analysis. The SP, PCR, and MCA modules were designed and tested on a standalone basis and then integrated for analysis of raw clinical samples. An automated XY stage was developed for magnetic bead-based DNA purification. In addition, a LED/CCD-based optical detection module was employed for real time PCR and MCA. Data analysis algorithms and protocols were implemented to remove noise and interpret data. This work culminated in proof of principle on-chip SP-PCR-MCA to detect ß2m DNA from human buccal cells in a modular and inexpensive system.
