Figure 2. TEM images of prepared AgNPs with various lecithin concentrations: (a) Klec/Ag = 0; synthesized AgNPs have a short life without stabilizer and linked one to another and appear
agglomerated silver particles; (b) Klec/Ag = 0.2, and (c) Klec/Ag = 2; lecithin molecules capped AgNPs and prevent them to link to one another.
