Fig. 2From: Duplex-specific nuclease and Exo-III enzyme-assisted signal amplification cooperating DNA-templated silver nanoclusters for label-free and sensitive miRNA detectionExcitation spectrum (blue curve) and emission spectrum (red curve) of DNA-templated AgNCs. Emission spectrum was recorded with excitation at 560 nm, and excitation spectrum was recorded for 630 nm emission wavelengthBack to article page
