Erratum: Nuclease Hydrolysis Does Not Drive the Rapid Signaling Decay of DNA Aptamer-Based Electrochemical Sensors in Biological Fluids (Langmuir (2021) 37:17 (5213−5221) DOI: 10.1021/acs.langmuir.1c00166)

Our original publication accidentally reported the full sequence of the cocaine-binding aptamer in Table 1 of the main text instead of the truncated variant used in the work. The correct sequence and its corresponding reference are marked in bold as follows. The “Chemicals and Materials” section should include the text, “Procaine hydrochloride, 6-hydroxyquinoline, and quinine hydrochloride dihydrate were purchased from Sigma-Aldrich.” We note that these corrections do not alter the results, significance, or discussion of our manuscript. They were errors missed during the proofing phase. However, correcting the aptamer sequence and specifying the chemical form of the targets employed are critical to ensuring reproducibility of ourwork. (Table Presented).
