- Abstract
The aim of the present study was to evaluate seed germination, embryonic axis length, toxicity, and antioxidant efficacy of silver nanoparticles synthesized (SNPs) from seaweed extract of Sargassum prismaticum V.D. Chauhan. The seaweed S. prismaticum extract was mixed with silver nitrate, change in colour from yellow to dark brown. The formation of SNPs is confirmed by the appearance signatory brown colour of the solution and a characteristic peak at 411 nm in the UV-Vis spectrum. FTIR spectrum shows 11 peaks. The S. prismaticum extract was subjected to XRD analysis for further confirmation of its crystalline nature. FESEM images were found that the SNPs were uniformly distributed and size ranging between 69.99 - 99.15 nm with spherical and cuboidal morphology. The obtained zeta potential value of SNPs through DLS method was had an average size of 94.73 nm. The seedling growth was positively affected by certain concentration of SNPs. For DWt (Dry Weight) of embryonic axis, All the SNPs concentration (25, 50 and 100%) significantly increases EAL (Embriyonic Axis Length) and DWt in all the three plant seeds. The highest percentage inhibition was 79.8% observed in algal extract at the concentration of 500 µg/mL. The IC50 value of algal SNP was 238.21 µg/mL and algal extract was 110.63 µg/mL. S. prismaticum extract SNPs react with earthworm Lampitomauritii in the mortality rate of 25% and 100% for 3 minutes. Overall, the biotransformation of silver nanoparticles utilizing S. prismaticum bioreagent is a low-cost, environmentally friendly approach with enormous biotechnological potential.
