2.1. AgClNPs and AgNPs synthesis
Corn husks were obtained from a local market; 20 g was weighed,
dried and ground with 40 ml of deionized water (DW). The NPs
synthesis was performed by adding a defined volume of 5 mM silver
nitrate (AgNO3) to five vials. Different corn husk extract volumes (1, 3,
5, 8 and 12 ml) were added to these vials. The final volumes were
adjusted to 25 ml to obtain AgNO3 concentrations of 2 mM. The effect
of the pH on the synthesis was studied by adjusting the pH with
ammonium hydroxide (NH4OH) or nitric acid (HNO3). The biosynthesis
was performed under regular interior illumination conditions,
constant stirring and ambient temperature
