The mean particle size 82.77 nm with a polydispersity index of 0.387, and − 30.8 mV zeta potential specifies the strong stability of the nanoparticles. Scn-AgNPs demonstrated promising wound healing potential, with around 67.72% of wound closure rate at 25 μg/mL concentration. Besides, It also displayed significant anti-inflammatory, antioxidant (in terms of DPPH (75.48%), ABTS (95.04%), SOD (73.92%) potential), antidiabetic properties (95.32% of α-amylase inhibition and 94.42% of α-glucosidase inhibition), and tyrosinase inhibition (27.07%) potentials. Furthermore, the Scn-AgNPs also exhibited significant antibacterial potential with the inhibition zones diameter ranging from 13.84 to 16.90 mm against all the three tested bacteria.Conclusion: The results indicated that Scn-AgNPs could be a potential candidate for various applications, including cosmetics for preparing antioxidant rich gels and nano formulations, in the biomedical field as a component of wound dressing, antibacterial dressing, drug carriers and drug delivery systems, and in environmental sectors as antibacterial agents, food packaging, food additives and in vitro/in vivo monitoring. This study highlights the use of sericin bio-waste materials into valuable resources, endorsing sustainability and enhancing the commercial value of silk-based bio-waste materials.Keywords: silk protein, sericin, bio-waste, anti-inflammatory, wound healing, antioxidant, antibacterial mode of action |
