Effects of storage conditions on the performance of an electrochemical aptamer-based sensor

“…1A). [5][6][7][8] In the absence of target, the aptamer exists in dynamic equilibrium and takes a predominantly unfolded state where the redox reporter is far from the gold surface, leading to relatively slow electron transfer. 9 Upon target addition, the aptamer undergoes binding-induced folding, moving the redox reporter closer to the gold surface and accelerating electron transfer.…”
