This paper describes a novel fluorescence label-free aptasensor to detect aflatoxin B 1 (AFB 1 ) by utilizing SYBR Gold, aptamer, and single-walled carbon nanohorns (SWCNHs). In the presence of AFB 1 , the conformation of AFB 1 -specific aptamer went through and the spatial structure of this specifi...
