*8.1. Temperature*

Temperature is an important factor in controlling the nature of NPs. Generally, biosynthesis processes using natural sources require temperatures ranging from room temperature to 100 ◦C [172]. Liu et al. synthesized Ag-NPs using *Cinnamomum Camphor* leaf extract at different temperatures including 70, 75, 80, 85, and 90 ◦C [173]. The temperature had impressively different effects on the nucleation kinetics constant k1 and growth kinetics constant k2 resulting in the generation of NPs with different sizes.
