Summary: Development of high-performance fluorescence sensors for pesticide has been a challenging task. Most existing fluorescence sensors use enzyme-inhibited strategy, which is expensive and prone to interference. Aptamer-based fluorescence sensors require intricate processes and expensive materials. In this study, a novel aptamer-based fluorescence system is developed for label-free, enzyme-free, and highly sensitive detection of profenofos pesticide. The system utilizes hybridization chain reaction (HCR)-assisted signal amplification and specific intercalation of N-methylmesoporphyrin IX (NMM) in G-quadruplex DNA to achieve improved detection performance.
