Corrigendum to “Aptamer-functionalized 2D photonic crystal hydrogels for sensitive and selective Hg²⁺detection” [J. Hazard. Mater. 511 (2026), 142176]

All corrections requested in this corrigendum are minor revisions to the original data, textual descriptions, and formatting details. These modifications only correct inaccurate and ambiguous contents in the original manuscript and do not alter the core findings, analytical results, interpretations, or the final conclusions of the paper. The overall scientific validity, integrity, and academic conclusions of the study remain completely unchanged.Formula (1) in Section 2.4 should be revised to (formula presented) Formula (2) in Section 2.4 should be revised to (formula presented) Table 1 should be revised to (table presented) limit of detection (LOD) should be revised to detection limit (DL). The authors regret1.Formula (1) in Section 2.4 should be revised to (formula presented) (Only the number 3 is under the square root in the denominator.)2.Formula (2) in Section 2.4 should be revised to (formula presented) (Only the number 3 is under the square root in the denominator.)3.Table 1 should be revised to (table presented) The minor data revisions are limited exclusively to the values presented in Table 1. No corresponding modifications are required for the main text of the manuscript. All textual descriptions, data interpretations, analysis discussions, and results summary contents related to Table 1 in the main text are accurate, consistent with the updated table data, and remain unchanged.4.limit of detection (LOD) should be revised to detection limit (DL).(Only the number 3 is under the square root in the denominator.)(Only the number 3 is under the square root in the denominator.)The minor data revisions are limited exclusively to the values presented in Table 1.
