In order to make a stable dendrimer dispersion in a phosphate buffered saline (pbs) solution, 10% of drug loaded dendrimers are added into the pbs solution in a glass vial. if the diameter of a dendrimer is 4.8 nm, compute the number of dendrimers present in each cm3. densities of the dendrimer and pbs solution are 1.28 and 1.07 g/cm3, respectively.
