dc.description.abstractWe report a novel multimode detection aptasensor with three signal responses (i.e., fluorescence recovery, enhanced Raman signal, and color change). The presence of adenosine induces the conformational switch of the adenosine aptamer (Apt), forming adenosine-aptamer complex and releasing quantum dots (QDs) from AuNPs, resulting in the recovered fluorescence, the enhanced Raman signal, and color change of the solution. The multimode signal recognition is potentially advantageous in improving the precision and reliability of the detection in complex environments compared to the conventional single-mode sensing system. The multimode detection strategy opens up a new possibility in sensing and quantifying more other target molecules. © 2014 Na Zhao et al.
