Overall properties of LPPPEI containing dec-ODN.

1Mean geometric diameter as determined by laser diffraction.2Standard Error Mean calculated on 3 different batches (n = 6).3Theoretical mass mean aerodynamic diameter estimated on the basis of the equation 2.4Experimental mass mean aerodynamic diameter ± geometrical standard deviation as evaluated by MSLI tests.5Percent ratio between dec-ODN actual and theoretical loadings. Dec-ODN theoretical loading was 0.140 nanomoles per mg of LPPPEI.6Percent ratio between PEI actual and theoretical loadings. PEI theoretical loading was 1.0 mg per 100 mg of LPPPEI.
