Competing Interests

Justin Cooper-White has read the journal’s policy and has the following conflicts: DMT and JJC-W are listed as inventors on an International Patent Application related to the work, number PCT/AU2012/001094. This patent is entitled “Substance Exposure Apparatus”, Australian Provisional Patent Application 2011903773, and International Patent Application No. PCT/AU2012/001094. The authors therefore confirm that this declaration of the existence of the patent and no other competing financial interests does not alter the authors adherence to all the PLOS ONE policies on sharing data and materials.
