Nanoparticle Size Characterization by DLS

Check if the same lab product or an alternative is used in the 5 most similar protocols
Particle size‐distribution measurement was performed by dynamic light scattering (DLS) using a ZetasizerTM Nano ZS machine (ZEN3600, Malvern, Kassel, Germany) with detection at an angle of 173° (back‐scattering). Samples were diluted in 10 mM NaCl with a dilution factor of 10 and measured in disposable cuvettes (Malvern). Samples were run consecutively in triplicates for 50 × 10 s at 20°C. Instrument was set to automatic attenuation and positioning. A refractive index of 1.39 and sample absorption of 0.01 were assumed for all EV‐measurements. High measurement quality was assured by analysing raw correlation data, the resulting correlation fits, and polydispersity indices.

DLS Characterization of Citrate-Stabilized AuNPs

Check if the same lab product or an alternative is used in the 5 most similar protocols
DLS measurements were performed with a Zetasizer Nano ZS instrument (Malvern Analytical). Citrate-stabilized AuNPs and NA-AuNPs in 2 mM citrate and 0.3× PBS buffer, respectively, were diluted to an optical density of 1, placed in disposable cuvettes (Malvern) and positioned for DLS measurement.

Nanoparticle Characterization by Zetasizer

Check if the same lab product or an alternative is used in the 5 most similar protocols
The zeta potential and nanoparticle
diameter were measured using a Malvern Zetasizer Nano ZS. The sample
was dispersed in MES/KCl (pH 6 and 7) and HEPES/KCl (pH 8) solutions
(50 mM/50 mM) and allowed to stand prior to measurements in disposable
cuvettes (Malvern). Measurements were conducted as three replicates;
average results were quoted using the standard deviation as the error.

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.
