Table 7 Comparison of green synthesis methods for metal nanoparticles using various plant extracts
Study | Plant extract | Type of nanoparticle | Particle size (nm) | Shape | Key activities/Properties |
|---|---|---|---|---|---|
Current work | Psidium guajava (Guava) | AgNPs | 9.038 (XRD), 7.531 (DLS) | Spherical | Antibacterial against S. aureus; Cytotoxicity against THLE2 and HepG2 cells |
Sana et al. [21] | Perilla frutescens crude polysaccharides (PFCPS) | AgNPs | 18.7–23.8 | Spherical | Antioxidant (DPPH, ABTS, Reducing power); Antibacterial against E. coli and K. pneumoniae |
Basavegowda et al. [20] | Artocarpus heterophyllus Lam. (Jackfruit) fruit extract | AuNPs | 20–25 (small spherical), 5 μm (large polyhedron) | A mixture of spherical and polyhedron | Antibacterial against E. coli and Streptobacillus; Synergistic effect with antibiotics |
Basavegowda et al. [22] | Saururus chinensis leaf extract | PdNPs | ~ 4 | Spherical | Antioxidant (DPPH: IC50 26.66 µg/mL); Anti-tyrosinase (85.95% at 100 µg/mL) |
