The average diameter of the synthesized AgNPs was calculated to be in the range of 10–25 nm. AgNPs exhibited promising antidiabetic activity as determined by inhibition of α-glucosidase (95.29% inhibition at 10 μg/mL and IC50 value of 2.10 μg/mL) and cytotoxicity (IC50 value 4.0 μg/mL as calculated from the slope equation) against HepG2 cells. Furthermore, they also exhibited moderate antioxidant activity (50.17% reduction of 1,1-diphenyl-2-picrylhydrazyl at 100 μg/mL) and antibacterial activity against four human pathogenic bacteria (as indicated by 8.70–11.10 mm inhibition zones on agar plates).Conclusion: In conclusion, the results confirm that food waste can be used in the synthesis of AgNPs and that the latter have the potential for applications in various fields including diabetic and cancer treatments as well as in biomedicine for the manufacture of antibacterial coatings in medical devices and instruments.Keywords: antibacterial, antidiabetic, antioxidant, cytotoxicity, garden pea, silver nanoparticles, Pisum sativum |
