Abstract

Target-triggered catalytic hairpin assembly lights up darkish DNA-templated silver nanoclusters through proximity-induced activation by a G-rich fluorescence enhancer. Beyond being label-free, this lighting-up fluorescence biosensor requires neither quenchers nor separation steps, greatly simplifying the operation.
