摘要

Background

Silver nanoparticles (AgNPs), valued for their antimicrobial activity, were incorporated into cotton and polyamide 66 textiles to assess durability and toxicity. Commercial and lab-synthesized AgNPs were applied with atmospheric plasma pretreatment to improve adhesion to fibers.

Results

AgNPs showed predominantly spherical morphology (~ 50 nm), confirmed by DLS and TEM, with composition verified by XRD and EDS. Pretreated textiles exhibited enhanced AgNP retention, though notable silver loss occurred after repeated laundering. Zebrafish embryo assays indicated no significant morphological or developmental toxicity, even at high concentrations.

Conclusions

The results support the safe application of AgNPs in antimicrobial textiles but emphasize the need for improved fixation to reduce silver loss. Further studies should address long-term environmental impacts and enhance nanoparticle durability, contributing to safer nanomaterial-based textile technologies.
