Large-volume Plasma Separation CD towards microbial detection in whole blood:
While POC devices are trending down in size, there remains a
biological limit on sample size and the corresponding
limit-of-detection. An example of this is Bacillus Anthracis, which
is present at 10 copies/mL in infected whole blood. Only by starting
with a 1 mL sample or larger, and only after amplification, can B.
Anthracis be detected by electrochemical or fluorescent techniques.
Therefore, there is a need for devices capable of processing samples
on the order of several mLs. The Madou lab has developed a
large-volume plasma separation CD that automates a classical technique
to separate plasma from a 2mL whole blood sample. The ultimate goal
of this project is to integrate the Plasma Separation CD, with a
real-time PCR CD, as part of an automated anthrax detection system.
This project is supported by the MF3 center at UC Irvine.
