The demand for antimicrobial textiles is rapidly
growing particularly in medical sector. In an
effort to develop a simple and efficient
antimicrobial treatment for cotton, layer-bylayer
deposition of chitosan and magnesium
lignosulfonate, followed by in situ synthesis of
silver (Ag) nanoparticles, was accomplished.
Lignin is exploited as a natural reducing and
stabilizing agent1,2, producing Ag nanoparticles
in amounts even larger than those obtained with
sodium borohydride as a strong reducing agent.
The influence of the number of bilayers (4 and
12) and initial concentration of AgNO3 solution
(10 and 20 mM) on antimicrobial activity of
cotton fabric against Gram-negative bacteria E.
coli, Gram-positive bacteria S. aureus, and C.
albicans, yeast was examined. The presence of
evenly scattered Ag nanoparticles all over the
fiber surface is confirmed by FESEM analysis
(Figure 1). The number of bilayers does not
affect the size of nanoparticles (~56 nm), but an
increa...se of bilayers results in greater Ag
content. The samples treated with 20 mM
AgNO3 solution contain more Ag than those
treated with 10 mM solution. The formation of
metallic Ag nanoparticles is confirmed by XPS
analysis.
Synthesized Ag nanoparticles provide excellent
antibacterial activity against bacteria S. aureus
(99.9 %), independent of the initial
concentration of AgNO3 and number of bilayers.
Larger content of Ag nanoparticles i.e., higher
initial concentration of AgNO3 solution leads to
considerably enhanced antibacterial activity
against E. coli. A similar trend is evident with
the C. albicans yeast, but the desired yeast
reduction of 99 % was not obtained.
