The effects of QDs on PCR efficiency was validated in real-time PCR system. The number indicates the corresponding concentration in nM level of QDs adding to the PCR mix. The results suggested that low concentration of CdTe QDs had no obvious effect on the PCR process but excess QDs result in inhibition.
