Optimization studies based on UV–visible spectral analysis for gold and silver nanoparticles production by C. sativa fiber extract.

Notes: The optimized parameters for F-AuNPs were as follows: reaction mixture ratio (extract:water) (A), temperature (B), time (C) and gold salt concentration (D). For F-AgNPs, an attempt was made to optimize silver salt concentration (E).

Abbreviations: aq, aqueous; C. sativa, Cannabis sativa; F-AgNPs, fiber-silver nanoparticles; F-AuNPs, fiber–gold nanoparticles; OD, optical density; temp opt, temperature optimization; UV, ultraviolet.
