Zeta potential was evaluated in a laser-Doppler anemometry using a Malvern Zetasizer (Malvern Instruments, Worcestershire, UK) with all determinations performed at 25 °C in aqueous media. The effective voltage used was 150 V. For zeta potential determinations, 5 mg of each formulation was weighed, placed in a flask, diluted with 50 ml distilled water and maintained in a sonicator for 5 min. Then the samples were introduced into a capillary cell (Cell Enhances Capillary®, Malvern Instruments), for zeta potential measurements. All formulations were analyzed in triplicate.

Zeta potential was determined by Laser-Doppler anemometry using a Malvern Zetasizer Nano S® (Malvern Panalytical, Malvern, U.K.). Measurements were carried out at 25 °C in aqueous solution. For this, 5 mg of each formulation was suspended in 50 mL of distilled water and stirred for 1 min. Then, the aqueous dispersion of NPs at a concentration of 100 µg/mL was placed in a capillary cell (Cell Enhances Capillary®, Malvern Panalytical, Malvern, U.K.) for zeta potential measurements. All formulations were analyzed in triplicate.

A Laser-Doppler anemometry with a Malvern Zetasizer (Malvern Panalytical, Malvern, UK) was employed for measuring the zeta potential of the NPs. Analyses were carried out at 25 °C in aqueous medium with the effective voltage set at 150 V. Briefly, an exact amount (5 mg) of each formulation was placed in a flask, diluted with distilled water (50 mL), and sonicated for a period of 5 min. For zeta potential estimations, each sample was placed in a capillary cell (Cell Enhances Capillary®, Malvern Panalytical, Malvern, UK). All formulations were analyzed in triplicate.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
