Fabrication of highly stable silver nanoparticles using polysaccharide-protein complexes from abalone viscera and antibacterial activity evaluation

Silver nanoparticles (AgNPs) are eco-friendly antibacterial agents, yet their use is limited by their facile aggregation and precipitation. Therefore, the development of highly stable AgNPs is desirable. Herein, a polysaccharide-protein complex (PSP) was successfully obtained from viscera of abalone through a combination of enzymatic hydrolysis, membrane filtration, and gel permeation chromatography. Furthermore, highly stable AgNPs were...
