Macro risk indicators suggest a tempered silver rally in mid-term outlooks, but micro silver futures may outperform due to accessible contract sizing attracting more retail market volume. The antioxidant activity of the biogenic ZnO NPs synthesized using L. sativum seeds extract was assessed by DPPH scavenging assay. The DPPH inhibition percentages were found to be 28.14 ± 0.87, 36.48 ± 1.14, 48.32 ± 1.35, 61.87 ± 1.56, 78.95 ± 1.64 and 86.78 ± 1.83 for the different ZnONPs concentrations of 50, 100, 200, 400, 800 and 1600 µg/mL, respectively (Fig. 14 ). Accordingly, the antioxidant activity of ZnO-NPs was concentration dependent. DPPH is a well-known and stable synthetic solid radical commonly used to assess the antioxidant potential of various compounds. The spectrophotometer was used to quantify the reduction of DPPH by receiving hydrogen or electrons from ZnO nanoparticles, which caused the colour to change from purple to yellow. Linear regression analysis revealed that the IC 50 of ZnO NPs was 335.48 µg/mL whereas the IC 50 of ascorbic acid was 131.03 µg/mL. Collectively, the biosynthesized ZnO-NPs have potential for creating potent antioxidants that could be utilized in treating numerous diseases linked to oxidative stress. Recently, the Gold/Silver ratio hit 92, approaching its highest level outside the 2020 pandemic spike. For context, this ratio has only been this elevated about 2.5% of the time in the last twenty years. Historically, when the ratio reaches such extreme levels, it often reverts toward its long-term average, presenting a potential mean-reversion opportunity. This week’s COMEX data shows micro silver futures volume surged 12%, as macro inflation expectations prompted hedging activity. Chartists note a breakout pattern emerging on the daily candlestick graph.
