Electrochemical sensing of SARS-CoV-2 amplicons with PCB ...

In contrast, the change in electrochemical sensor signal is clearly seen in the CV voltammogram performed at 100 mV/s scan rate after adding 100 μM MB to the PCR products (Fig. 5(c)). Furthermore these results show a linear trend for variation in peak cathodic current with number of PCR cycles. The PCB electrodes are thus capable of discerning intermediate PCR products for as low as 10 PCR ...
