Silver nanoparticles (AgNPs) offer potent antifungal activity, but their practical use is limited by instability, aggregation, and potential toxicity. This study aims to develop a safe, stable, and highly effective antifungal agent of carbohydrate\u2010derived positively\u2010charged glycopolymer\u2010stabilized AgNPs (PGM@AgNPs) nanocomposites.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS<\/jats:title>\n                    <jats:p>\n                      PGM@AgNPs exhibited an exceptionally narrow size distribution (7.41\u2009\u00b1\u20094.27\u2009nm).

Transcriptomic analysis revealed that the antifungal mechanism involves inducing oxidative stress, disrupting cellular integrity, and triggering autophagic cell death. Moreover, PGM@AgNPs showed negligible hemolysis and low cytotoxicity toward L929 cells and zebrafish.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSION<\/jats:title>\n                    <jats:p>The carbohydrate\u2010derived PGM@AgNPs combine superior stability, enhanced antifungal efficacy, and favorable preliminary biocompatibility.
