Characterization of the formulations OVA:NPL. Size (Z-average), PDI (polydispersity index) and Zeta potential are measured in triplicate with a Zetasizer NanoZS.

NPL	76.07	0.211	+ 44.2 ± 10.15
OVA	1.976	0.477	− 7.77 ± 5.60
OVA:NPL 1:0.5 w/w	2782.67	1	+ 25.17 ± 6.937
OVA:NPL 1:3 w/w	76.71	0.261	+ 33.27 ± 9.173
OVA:NPL 1:5 w/w	62.39	0.236	+ 33.47 ± 8.417
