A novel device for the determination of liposome/water partition coefficients

Green Fluorescent Carbon Dots with Critically Controlled Surface States: Make Silk Shine via Feeding Silkworms

“…The oil/water partition coefficient (Lg P) is commonly used to quantify lipophilicity in the biomedical fields, and here n -octanol and PBS solution are chosen as the solvents. The shake flask method is employed to test the Lg P of G-CDs. − Figure f shows that only the upper n -octanol layer is luminescent under UV light, verifying G-CDs are lipophilic. According to the absorbance values of the upper and lower layers as well as standard curves, the retention concentrations of G-CDs in the two layers after sufficient distribution are calculated to be 13.209 and 0.090 μg·mL –1 , respectively (Figure g and h).…”
