The dry diameter and size distribution
of the NPs were measured
with TEM. TEM images were obtained with an FEI Tecnai C2 BioTWIN electron
microscope with a 120 kV accelerating voltage. Samples for TEM were
prepared by placing a drop of diluted sample on a 400 mesh carbon-coated
copper grid previously exposed to plasma for 10 s. The average particle
diameter and size distribution were determined by the measurement
of the diameter of more than 200 particles. The hydrodynamic diameter
and size distribution of the particles dispersed in DDW were measured
at rt with a particle analyzer, model NANOPHOX (SympatecGmbH, Germany).
Electrokinetic properties (ζ-potential) of the formed particles
were measured using a titration method, from pH 2.5 to 10.9 with 0.1
M HCl and 0.1 M NaOH. The measurements were measured at a constant
ionic strength of 0.1 M. The ζ-potential of the formed particles
was measured by a ζ-potential analyzer model Zetasizer 3000
HSa (Malvern Instruments, UK).
Elemental analysis was performed
with a PerkinElmer 2400 series
II analyzer, by the analytical laboratories of the Hebrew University,
Jerusalem. Phosphorus content was determined using the oxygen flask
combustion method followed by ion chromatography analysis using a
Dionex IC system.

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.
