The superscript refers to the n th multiplicity. . Results obtained at the coarse-grained level using the three mapping schemes above ((S)Na-Na, Na-N0, P1-C5) were systematically compared with data obtained using the atomistic model (Table ). The density values for the pure PLGA16 samples were 1.35±0.003 and 1.217±0.05 g/cm 3 at CG and UA resolution, respectively. For higher molecular weights, PLGA64, samples retuned slight larger values with 𝛿 equal to 1.37±0.07 and 1.27±0.003 g/cm 3 at CG and UA resolution, respectively.
