One-pot, green synthesis of gold nanoparticles by gelatin and investigation of their biological effects on Osteoblast cells

- Biosynthesis of gold nanoparticles (AuNPs) in the presence of gelatin biopolymer.
- Gelatin employed as reducing, growth controlling and stabilizing agent for AuNPs.
- Gelatin concentration establishes the shape and size of gold nanoparticles.
- Dark-field images confirm the AuNPs@gelatin efficient internalization into cells.
- Cells treated with AuNPs@gelatin present enhanced growth and proliferation rates.
