Size and Polydispersity Index of Demineralized Dentin Matrix Liposomes

	TBS liposomes	1 μg/mL DDM liposomes	10 μg/mL DDM liposomes	100 μg/mL DDM liposomes
Average size ± SD (nm)	122.9 ± 37.6	124.8 ± 37	134 ± 46.1	124.2 ± 39.5
PDI	0.164	0.151	0.1825	0.177

A Zetasizer Nano ZS was used to measure the average size and PDI of each batch of liposomes (0–100 μg/mL) by dynamic light scattering (n = 8 ± SD).

DDM, demineralized dentin matrix; PDI, polydispersity index; SD, standard deviation; TBS, Tris-buffered saline.
