Fig. 3From: RCA-Based Biosensor for Electrical and Colorimetric Detection of Pathogen DNAI-V characteristic curve for the detection of 0.05 μM target DNA after introduction of 0.5, 5.0, and 50 μM of HAuCl4. Also, the Au electrode treated with 50 μM of HAuCl4 after DNA amplification reaction without the target DNA was demonstrated as a control groupBack to article page
