Stability experiment of each Au nanoparticle type in PBS solution. a Size variation of each Au nanoparticle with time and b absorption change of OD values at 800 nm obtained using a microplate reader. Each sample was scanned 6 times. DLS experimental data were obtained through triplicate measurements
