There is an error in the abstract of this paper. The correct abstract is given below:

An ultrasensitive nucleic acid biosensor for the direct detection of attomoles nucleic acid in 1.0-5.0 μl droplets is described which can be used for detection of cancer marker genes in mRNA extracted from human breast tissues without a RT-PCR step.

The Royal Society of Chemistry apologises for this error and any consequent inconvenience to authors and readers.
