were synthesized via plama-liquid interaction using Ag(NH3)2OH as the silver source and sucrose as the dispersant, with AgNO3 solution chosen as the reference precursor. It was shown that Ag(NH3)2OH provides significantly higher conversion efficiency and generate Ag nanoparticles with smaller average size and narrower size distribution Besides, AgNPs obtained from Ag(NH3)2OH also showed higher antibacterial activity against E. coli at the same concentration compared with Ag NPs obtained from Ag+ as well as commercial samples purchased from Sigma-Aldrich. It is demonstrated that using Ag(NH3)2OH for Ag nanoparticles synthesis with microplasma-assisted approach is beneficial to both, the synthesis process throughput and product quality.
