Polysaccharide\u2010based hydrogels have become a research hotspot due to their favorable biocompatibility and tunable functional properties.

The QDTA hydrogel demonstrated a suitable gelation time (60\u2013240\u00a0s) and exhibited significant antibacterial activity against both\n                    <jats:italic>Staphylococcus aureus\u00a0(S.\u00a0aureus)<\/jats:italic>\n                    and\n                    <jats:italic>Escherichia coli\u00a0(E.\u00a0coli)<\/jats:italic>\n                    , with average inhibition rates of 98.96% and 98.91%, respectively. Moreover, it showed a biodegradation rate of up to 90% within 10 days, making it suitable for\n                    <jats:italic>in vivo<\/jats:italic>\n                    wound healing applications.\n                    <jats:italic>In vivo<\/jats:italic>\n                    experiments further confirmed that QDTA hydrogel effectively promoted tissue regeneration and wound healing by exerting antibacterial effects, scavenging reactive oxygen species (ROS) in the wound site, and enhancing cell migration, ultimately achieving a wound closure rate of \u224899.75% by day 14. These results highlight the significant potential of QDTA hydrogel as an effective wound dressing for clinical application.\n                  <\/jats:p>","DOI":"10.1002\/mabi.202500084","type":"journal-article","created":{"date-parts":[[2025,5,16]],"date-time":"2025-05-16T02:20:19Z","timestamp":1747362019000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Development of an Injectable Synergistically Crosslinked Polysaccharide Hydrogel with Antioxidant and Antibacterial Properties for Promoting Wound Healing"],"prefix":"10.1002","volume":"25","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-8939-6941","authenticated-orcid":false,"given":"Rongrong","family":"Li","sequence":"first","affiliation":[{"name":"Key Laboratory for the Structure and Function of Polysaccharides in Traditional Chinese Medicine (Administration of Traditional Chinese Medicine of Jilin Province) Beihua University  Jilin 132013 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-8781-5519","authenticated-orcid":false,"given":"Yue","family":"Zhao","sequence":"additional","affiliation":[{"name":"Key Laboratory for the Structure and Function of Polysaccharides in Traditional Chinese Medicine (Administration of Traditional Chinese Medicine of Jilin Province) Beihua University  Jilin 132013 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-8142-1689","authenticated-orcid":false,"given":"Shangbo","family":"Zhang","sequence":"additional","affiliation":[{"name":"Medical Technology College Beihua University  Jilin 132013 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yongchao","family":"Liu","sequence":"additional","affiliation":[{"name":"Medical Technology College Beihua University  Jilin 132013 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chuanxi","family":"Chi","sequence":"additional","affiliation":[{"name":"Key Laboratory for the Structure and Function of Polysaccharides in Traditional Chinese Medicine (Administration of Traditional Chinese Medicine of Jilin Province) Beihua University  Jilin 132013 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dongjie","family":"Wu","sequence":"additional","affiliation":[{"name":"Key Laboratory for the Structure and Function of Polysaccharides in Traditional Chinese Medicine (Administration of Traditional Chinese Medicine of Jilin Province) Beihua University  Jilin 132013 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-9838-6702","authenticated-orcid":false,"given":"Jianxi","family":"Song","sequence":"additional","affiliation":[{"name":"Key Laboratory for the Structure and Function of Polysaccharides in Traditional Chinese Medicine (Administration of Traditional Chinese Medicine of Jilin Province) Beihua University  Jilin 132013 China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,5,15]]},"reference":[{"key":"e_1_2_8_1_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0196-0644(88)80351-2"},{"key":"e_1_2_8_1_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41580-024-00715-1"},{"key":"e_1_2_8_1_3","doi-asserted-by":"publisher","DOI":"10.3390\/biom10081169"},{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1159\/000339613"},{"key":"e_1_2_8_2_2","doi-asserted-by":"publisher","DOI":"10.1021\/acs.biomac.7b01764"},{"key":"e_1_2_8_3_1","first-page":"2674","volume":"3","author":"Fawzy A.","year":"2023","journal-title":"Int.
