Synthesis of antibacterial hydroxypropyl methylcellulose and silver nanoparticle biocomposites via solution plasma using silver electrodes

Yu-Been Ko et al.

Summary: Biocomposites of hydroxypropyl methylcellulose (HPMC)/silver nanoparticles (AgNPs) were synthesized through the solution plasma process (SPP). The synthesized biocomposites exhibited a peak near 400 nm in UV-Vis spectroscopy, which increased with the concentration of HPMC and discharge time. TEM and SEM/EDS analyses revealed well-dispersed spherical AgNPs with sizes ranging from 2-18 nm in porous HPMC matrices. TGA analysis confirmed the thermo-stability of the biocomposites. The HPMC/AgNPs biocomposites showed inhibition zones ranging from 8-14.3 mm against bacterial growth, with minimum inhibition concentrations of 10-15 μg/mL for Gram-negative bacteria and 25-30 μg/mL for Gram-positive bacteria. The biocomposites were non-toxic to HEK293 cells up to a concentration of 125 μg/mL. These findings suggest that the synthesis of antibacterial agents using silver electrodes in the HPMC matrix via SPP can be an efficient and safe method for developing biopolymer-based antimicrobials and wound healing biomaterials.
