Efficient wound dressings are indispensable for repairing infected wounds. Isochlorogenic acid A (IAA), the core active ingredient of Shanyinhua, has superior anti-inflammatory and antibacterial effects. However, low water solubility and weak structural stability restrict its direct application in wound treatment. In this work, IAA@Fe(III) nanoparticles (IAA@Fe(III) NPs) were synthesized through self-assembly and loaded into cross-linked amylopectin (Amy)\/carboxymethyl chitosan (CMCS) (AC hydrogel) to construct Amy\/CMCS@NPs composite dressings. Characterizations demonstrated that nanoparticles displayed a uniform spherical shape with a size of 114.20 \u00b1 2.29 nm and stable coordination. The hydrogel featured a dense porous structure and outstanding mechanical performance, self-healing ability, adhesion, and swelling properties. In vitro tests proved that 50 mg\/mL composite hydrogel exerted nearly 100% bacteriostatic activity against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus), with good biocompatibility, and enhanced cell migration capacity. In vivo assays indicated an 86.5% wound healing rate at day 7. This dressing could downregulate Tumor Necrosis Factor-\u03b1 (TNF-\u03b1) and Interleukin-1\u03b2 (IL-1\u03b2), upregulate Cluster of Differentiation 31 (CD31) and Vascular Endothelial Growth Factor (VEGF), and accelerate wound repair. This study provides a theoretical and experimental basis for the exploitation of IAA-based wound dressings and high-value utilization of Shanyinhua resources.<\/jats:p>","DOI":"10.3390\/gels12070637","type":"journal-article","created":{"date-parts":[[2026,7,17]],"date-time":"2026-07-17T03:12:38Z","timestamp":1784257958000},"page":"637","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Preparation of Multifunctional Hydrogel Loaded with Isochlorogenic Acid A\/Fe3+ Co-Assembled Nanoparticles and Its Application in Skin Wound Repair"],"prefix":"10.3390","volume":"12","author":[{"given":"Hui","family":"Li","sequence":"first","affiliation":[{"name":"School of Pharmacy, Zunyi Medical University, Zunyi 563000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Danli","family":"Peng","sequence":"additional","affiliation":[{"name":"School of Pharmacy, Zunyi Medical University, Zunyi 563000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhijia","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Pharmacy, Zunyi Medical University, Zunyi 563000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuping","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Pharmacy, Zunyi Medical University, Zunyi 563000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xingyu","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Pharmacy, Zunyi Medical University, Zunyi 563000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yongmei","family":"Jiang","sequence":"additional","affiliation":[{"name":"School of Pharmacy, Zunyi Medical University, Zunyi 563000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xin","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Pharmacy, Zunyi Medical University, Zunyi 563000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9286-1761","authenticated-orcid":false,"given":"Lei","family":"Zhu","sequence":"additional","affiliation":[{"name":"School of Pharmacy, Zunyi Medical University, Zunyi 563000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yanlei","family":"Guo","sequence":"additional","affiliation":[{"name":"Chongqing Academy of Chinese Materia Medica, No.34 Nanshan Road, Nan\u2019an District, Chongqing 400065, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1280-2468","authenticated-orcid":false,"given":"Yongai","family":"Xiong","sequence":"additional","affiliation":[{"name":"School of Pharmacy, Zunyi Medical University, Zunyi 563000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9977-1766","authenticated-orcid":false,"given":"Gang","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Pharmacy, Zunyi Medical University, Zunyi 563000, China"},{"name":"Guizhou Key Laboratory of Modern Traditional Chinese Medicine Creation, Zunyi 563000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,7,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Zhang, W., Dong, Q., Peng, Z., Su, L., Liu, H., Yi, Y., and Mei, L.
