Abstract
The present invention provides substrates and apparatuses for efficient, rapid and specific capture, and optimal recovery, of nucleic acids, as well as methods of their use. The substrate is porous in nature and has a capture polynucleotide capable of hybridizing to a target nucleic acid immobilized thereon. Upon flowing a sample containing or suspected of containing the target nucleic acid through the porous substrate, the target nucleic acid is rapidly captured. Following capture, the target nucleic acid can be efficiently recovered for subsequent use.
