<i>Hydrilla verticillata</i> defends against toxic ionic Ag through its biotransformation into Ag nanoparticles
The study examined the effects of silver ions (Ag<sup>+</sup>). Results indicated that treatment with 1 mM AgNO<sub>3</sub> for 36 h led to a 5-fold reduction in MDA levels and a 3-fold decrease in Proline. Additionally, a color change in the AgNO<sub>3</sub> solutions, from a clear, colorless solution to a brown, colloidal suspension. The UV-Vis absorption spectra of these colloidal solutions exhibited a plasmon resonance band at 430-480 nm. A peak at this position confirms the presence of AgNPs. TEM coupled with SAED revealed the presence of crystalline spherical AgNPs in the size range of 5-50 nm in the brown colloidal solution. These results suggest that Hydrilla biotransforms ionic silver into AgNPs.
