Pre-formulation studies are conducted each time new nanoparticulate formulations are in
development to the selection of a satisfactory drug delivery system. We hypothesized that
laser diffraction technique could be used as an initial screening, being an excellent tool to
save time and reduce the number of necessary tests to select formulations. We built radar
charts based on laser diffraction data as a new approach to determine the fingerprints of
nanocarrier formulations in order to select promising drug delivery systems. To validate our …
