Correction: Tao et al. Development of a Label-Free Electrochemical Aptasensor for the Detection of Tau381 and its Preliminary Application in AD and Non-AD Patients’ Sera. Biosensors 2019, 9, 84

Text Correction

In the original publication [1], a correction has been made to Section 3.7, Paragraph 1. The revised version is as follows:

Figure 8 shows the current response of a blank control (a young man’s serum), a Non-AD patient, and an AD patient (I_{Blank control} < I_{Non-AD patient} < I_{AD patient}). In Table 3, we chose five Non-AD patients and AD patients. Their tau381 levels are represented by the mean value ± SD. The detection contents of Non-AD patients ranged from 100 ± 6 pM to 520 ± 74 pM, and AD patients ranged from 1778 ± 86 pM to 4612 ± 62 pM, suggesting that the aptasensor could screen patients with AD and Non-AD, in excellent agreement with the results from an ELISA kit.

Error in Table

In the original publication [1], there was a mistake in Table 3 as published. When two different methods were used to test the same batch of samples, the data obtained were identical. Subsequently, we carefully verified the data and corrected

Table 3. Assay results of clinical serum samples using aptasensor and ELISA Kit.

	Sample No.	Content Detected with the Aptasensor (Mean ± SD, pM)	Content Detected with ELISA Kit (Mean ± SD, pM)
Non-AD Patient	1	100 ± 6	115 ± 41
	2	163 ± 58	128 ± 26
	3	520 ± 74	553 ± 31
	4	248 ± 62	274 ± 26
	5	269 ± 67	295 ± 38
AD Patient	1	1778 ± 86	1833 ± 58
	2	4022 ± 59	4057 ± 54
	3	3883 ± 61	3923 ± 42
	4	4612 ± 62	4730 ± 51
	5	3558 ± 55	3666 ± 45

based on the feedback from the Editorial Office. The corrected Table 3 appears below.

The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
