The candle ccPCR system productively amplified hepatitis B virus 122 base-pairs DNA fragment. The detection sensitivity can achieve at an initial DNA concentration to 5 copies per reaction. The results also show that the candle ccPCR system can operate functionally even the ambient temperature varies from 7 °C to 45 °C. These features imply that the candle ccPCR system can provide robust medical detection services. ? 2013 AIP Publishing LLC.[SDGs]SDG3Viruses; Detection sensitivity; DNA concentration; DNA fragment; External temperature; Hepatitis B virus; Phase Change; Thermal control; Polymerase chain reactionPolymerase chain reaction with phase change as intrinsic thermal controljournal article10.1063/1.48034422-s2.0-84983718347
