Study on antibacterial properties and cytotoxicity of seacell fibers filled with silver nanoparticles

In order to determine the antibacterial properties and cytotoxicity of the silver nanoparticles-filled seacell fibers,the qualitative and quantitative inhibition trials of the silver nanoparticles-filld seacell fibers against Staphylococcus aureus and Escherichia coli are investigated.The cytotoxicity tests of the silver nanoparticles on the L-02 cell lines are conducted to evaluate the safty with MTT cytotoxity assay.The results showed that more than 75% bacteria are inactivated when Staphylococcus aureus(AATCC25923) and Escherichia coli(AATCC25922) are incubated with 0.2% silver nanoparticles-filled seacell fibers for 4 h.MTT cytotoxicity test showed that the cell relative growth rates are over 90.0% and the cytotoxicity is about 1 degree(no MTT cytotoxity).The silver nanoparticles-filled seacell fibers show high antibacterial properties and less cytotoxicityl and can be used as a new type of textile material.
