Green synthesis, characterization and physiological stability of gold nanoparticles from Stachys lavandulifolia Vahl extract

- Gold nanoparticles were synthesized using an aqueous extract derived from Stachys lavandulifolia Vahl.
- The method is biomedically nontoxic, economically affordable and practically simple.
- Gold nanoparticles are most probably capped with compounds, able to cross the blood-brain barrier.
- The synthesized gold nanoparticles are stable in physiological condition and over time.
