Other important parameters are the encapsulation efficiency, EE%, namely the ability to encapsulate the drug within the NP system, and drug loading, amount of total drug loaded over the total nanporaticle weight: , , parameters estimated using High-Performance Liquid Chromatography (HPLC), see e.g
The solid was washed with ethanol (30 mL) and ether (30 mL)
Glutathione works gradually, so patience is essential
Additionally, they protect the skin from oxidative stress and promote collagen synthesis for a smoother and more radiant complexion
The samples were centrifuged (10,000 g , 10 min) and 20 L of the supernatants plus 60 L of 0.66 mg/mL DTNB solution, 60 L of 0.66 mg/mL -NADPH (Sigma) and 60 L of 3.33 units/mL glutathione reductase (Sigma) were used for DTNB assay
