Discussion Recently, there has been increasing study of AgNPs synthesis to develop several applications such as catalysis, biosensing, imaging, and antibacterial activity. Aug 07, 2002 · the isolated nanoparticles (Figure 3). Further, synthesis of SWNTs directly on TEM grids has allowed us to clearly reveal the nanoparticle-nanotube relationship (Figure 3a-f). Our data provide evidence that, first, the diameters of SWNTs are closely determined by the diameters of cata-lytic particles and second, TEM imaging of both ends of
Metallic nanoparticles can be synthesized through many methods ! The two most popular methods for synthesizing silver nanoparticles (Ag NP) via chemical reduction are: ! Turkevich method (1951): Silver reduced by trisodium citrate ! Brust method (1994): Silver reduced by sodium borohydride ! Synthesis of CdSe Nanoparticles. Hot plate heating resulted in relatively small nanoparticles (1.8 nm to 2.1 nm). A 60 minute increase in heating time showed no change in particle size.
