Abstract: A method comprises: sorbing a sample solution comprising nucleic acids to a sample receiving portion of a quartz fiber filter by contacting the sample solution with the sample receiving portion; and washing the sample receiving portion while keeping most of nucleic acids around the sample receiving portion by flowing a wash solution through the sample receiving portion under a wicking force directed away from the sample receiving portion. An associated apparatus is also provided.
