主 题:Silver nanoparticles Whey protein isolate Chloride Liquid chemical reduction method
摘 要:Nano metal materials have been widely explored to be applied in medical,environmental,and material *** these nanoparticles,especially silver nanoparticles(AgNPs),have drawn increasing attention for antimicrobial *** researchers are keen on the development of the biologically friendly capping reagents for the synthesis of AgNPs,instead of unfriendly organic *** this study,the liquid chemical reduction method was used to synthesize AgNPs with edible whey protein isolate(WPI)as a capping *** WPI-AgNPs had a broad size distribution(average diameter of 138.6 nm),and their dimensions could be readily controlled in the range of 22.5-149.6 nm by introducing different concentrations of ***,it was confirmed that WPI-AgNPs were formed through two mechanisms,which were respectively reduced in situ(without the addition of NaCl)and ex situ(in presence of NaCl)to yield silver *** WPI-AgNPs synthesized in presence of 10 mM of NaCl as mediation reagent were stable at room temperature or 4℃ up to 3 ***,the synthesized WPI-AgNPs had a good antibacterial activity toward pathogens including Gram-negative *** and Gram-positive *** results shed light on method and capping reagent to stabilize silver nanoparticles,which highlighted the potential of WPI and chloride in metal nanoparticle synthesis.
