Aptamer‐based fluorescent sensor for highly sensitive detection of methamphetamine

Yandan Wang,
Zheyu Wang,
Yishuo Tong
et al.

Abstract: The construction of a fluorescence aptamer sensor was achieved by employing the fundamental principle of fluorescence resonance energy transfer. By employing molecular modeling technologies to identify the binding site, the high‐affinity aptamer APT‐40nt was derived from the whole sequence and utilized on the graphene oxide (GO) fluorescent platform for the purpose of achieving a highly sensitive detection of methamphetamine (METH). The aptamer tagged with fluorescein (FAM) dye undergoes quenching in the prese… Show more
