ABSTRACT:
A handheld and portable extraction device is directed to a microfluidic-based system to be used in the field to extract and purify an analyte, preferably a nucleic acid, from a fluid-based sample. Preferably, the fluid-based sample is water-based. The fluid-based sample can also be a biological fluid sample. The handheld and portable extraction device includes a syringe-like device coupled to a purification chip. The purification chip is preferably included within a chip block which is removable from the remaining portion of the handheld and portable extraction device. The analyte collected within the purification chip can be later removed and collected for analysis.
