Synthesis, characterization and optical properties of gelatin doped with silver nanoparticles

- Silver nanoparticles were synthesized by chemical reduction method.
- TEM studies showed that the average particle size of Ag NPs was about 55 nm.
- Reduction of optical band gap of gelatin was achieved under addition of silver nanoparticles.
- There is noticeable color gradient between gelatin and doped samples.
