WebHere, we report an efficient target recycling amplification process (TRAP) for the digital detection of miRNAs using photonic resonator absorption microscopy. We achieve multiplex digital detection with sub-attomolar sensitivity in 20 minutes, robust selectivity for single nucleotide variants, and a broad dynamic range from 1 aM to 1 pM.

From Figure 5, the Q value increases unexpectedly, in spite of increasing the absorption loss by the metals. We can interpret that the field enhancement exceeds the increase of the absorption loss.
