A method comprising loading sample into at least two sample chambers, subjecting the sample portions in each sample chamber to at least a first amplification step, and determining whether each sample portion contains at least one molecule of a target nucleic acid. If a sample portion contains at least a single molecule of the target nucleic acid, it would attain a detectable concentration of the target nucleic acid after a single round of amplification. Also, a method for detecting whether at least one molecule of a first target nucleic acid is present in a first sample and detecting whether at least one molecule of a second target nucleic acid is present in a second sample. Also, a microfluidic device comprising sample chambers comprising respective ingredients which will react with respective target nucleic acids if contacted with the target nucleic acids and subjected to a round of amplification. |
