A wide linear range of 0.100 nM to 1.00 μM with a low detection limit of 93.0 pM was obtained. The aptasensor displayed excellent selectivity toward Aβ40-O in contrast to other possible interfering analogs (Aβ40 monomer, Aβ42 monomer, and oligomer) at × 100 higher concentrations. The recoveries for Aβ40-O-spiked artificial cerebrospinal fluid and healthy human serum were 94.0~104% and 92.8~95.4%, respectively. The electrochemical aptasensor meets the demands of clinic determination of Aβ40-O, which is significant for the early diagnosi
