A novel fluorescent structure-switching aptasensor for the sensitive detection of acrylamide based on AuNPs-assisted separation of ssDNA

Fluorescent aptasensor was developed for acrylamide (AAm) detection by utilizing the adsorption effect of Au nanoparticles (AuNPs) and fluorescence properties of SYBR Green I (SGI) towards double-stranded DNA (dsDNA). Compared to the binding of aptamer with AAm, the higher affinity of aptamer with c...
