Abstract:
1. The authors used the original ketamine aptamer sequence by referring to the research paper of Liu group (RSC Advance, Volume 9, 12 November 2019, page 36884–36889), but we apologize for not referring to the paper in material and methods of this article. Accordingly, the corrected content in the “Material and methods” was attached to this corrigendum. The authors apologize once again for any inconvenience caused. 2. Material and methods. 2.1. Chemicals. The original ketamine aptamer (Ket-40) was used from a sequence selected by the Liu's group (Hong Chen, Yun Zou, Xue Jiang, Fangqi Cao and Wenbin Liu, An enzyme-free FRET nanoprobe for ultrasensitive ketamine detection based on ATP-fueled target recycling, RSC Advance, 2019, 9, 36884). Six-carbon thiol (-SH-C6) and methylene blue (MB) were labeled on the 5′ and 3′ end of the Ket-38 aptamer, respectively. All aptamers used in this work were synthesized by Sangon Biotechnology Co., Ltd. (Shanghai, China) and were purified by HPLC. The oligonucleotides were dissolved in 10 mM tris buffer (pH 7.4) to form an aptamer solution (100 μM) that was stored at − 20 °C for further use. The sequences used in this work were as follows: Ket-40: 5′-GGG GGG ACG GGG CGG GAC GTG GTG TGT GGT TCG TGT CCC C-3′. Ket-38: 5′-GGG GGA CGG GGC GGG ACG TGG TGT GTG GTT CGT GTC CC-3′. Ket-36: 5′-GGG GAC GGG GCG GGA CGT GGT GTG TGG TTC GTG TCC-3′. Ket-34: 5′-GGG ACG GGG CGG GAC GTG GTG TGT GGT TCG TGT C-3′. Ket-38-MB: 5′-HS-C6-GGG GGA CGG GGC GGG ACG TGG TGT GTG GTT CGT GTC CC-MB-3′. 2. For “Data availability”, the authors selected the wrong option in the system. The correction is as follows: Data availability. Data will be made available on request. 3. We have reorganized the list of foundations and supporters. The correct funding of the acknowledgments section in our manuscript is the following: Acknowledgments.
