The Coated Paper with Silver Nanoparticles and its Antibacterial Activity

A simple method was achieved to develop a coating of silver nanoparticles on paper using ultrasonic radiation. Silver nanoparticles were prepared by the chemical reduction method using triethylene glycol as a reducing agent. UV-Vis spectrometry was used to characterize the synthesized silver nanoparticles in solution. The coated papers were characterized the surface features by scanning electron microscopy (SEM) and energy dispersive spectrum (EDS). The particle size distribution was 78 – 311 nm in diameter depending on ultrasonication time. The coated papers revealed the most effective in the antibacterial activity against both Staphylococcus aureus ATCC 25923^Tand Escherichia coli ATCC 25922^T.
