Correction to: Flexible electrostatic hydrogels from marine organism for nitric oxide-enhanced photodynamic therapy against multidrug-resistant bacterial infection
This correction addresses an inadvertent misplacement of Fig. 4b3 during figure reorganization in the original article published in Science China Materials, volume 65, issue 10, 2022, page 2850 (DOI: 10.1007/s40843-022-2024-6). The corrected Fig. 4b is presented herein. The authors confirm that this correction does not affect the results, conclusions, text, or figure caption of the original work. The correction was requested by the authors and received on 6 January 2026, accepted on 8 January 2026, and published online on 10 February 2026. The original study introduced flexible electrostatic hydrogels derived from marine organisms for nitric oxide-enhanced photodynamic therapy against multidrug-resistant bacterial infections. The correction ensures the accurate representation of experimental data, maintaining the integrity of the scientific record.
