Here, we introduce an electricity-free centrifuge platform based on a manual centrifuge. The provided centrifugal force is sufficient to produce a plasma purity of 99 separated in as little as 2−3 min. 
We then performed an immunoassay on a paper devicethe results were observed by a portable reader. As a result, the detection limit of the C-Reactive Protein is 1 ng/mL, with a total turnaround time of 7 min.

The plasma can then be testedanalyzed using a paper devicea portable reader at the point of need.

We expected these techniques can be used for the applications of personalized medicineprecision medicine.
