Comparison of gold particles loaded within exosomes through cellular biomineralization and manual benchtop preparation. Gold nanoparticle containing exosomes formed A,B) through cellular reduction of HAuCl₄ with the addition of iron (II) chloride to promote cellular production of ROS/RNS and C–E) through benchtop synthesis via mixing of exosomes with HAuCl₄.
