Figure 2From: Fabrication of silver nanoparticles from leaf extract of Butea monosperma (Flame of Forest) and their inhibitory effect on bloom-forming cyanobacteria Synthesis of SNPs using different leaf extract concentrations. (A) Control flask containing 0.01 M AgNO3. (B) Visible color change in 0.01 M AgNO3 solution after addition of 0.5% leaf extract solution. (C) Visible color change in 0.01 M AgNO3 solution after addition of 1.0% leaf extract solution.Back to article page
