Preparation of Surface-Enhanced Raman Scattering Substrates Based on Immobilized Silver-Capped Nanoparticles

<div>Transmission electron microscopy images of the synthesized nanoparticles. After the synthesis, a droplet of the colloid has been dried out on a copper grid in all cases. (a) AgNO<sub>3</sub> reduced with NH<sub>2</sub>OH·HCl. (b) AgNO<sub>3</sub> reduced with polyvinylpyrrolidone-10000. (c) AgNO<sub>3</sub> reduced with polyvinylpyrrolidone-29000.</div>
