Characterization of variant NPs.

NP’s Group	Particle Size (nm)	Zeta Potential (mV)	PDI
GE	91.90 ± 44.53	18.4 ± 4.4	0.30 ± 0.20
GEH	277.40 ± 73.00	−13.2 ± 4.1	0.38 ± 0.18
GEH-RGD	158.10 ± 11.06	12.9 ± 4.1	± 0.03

Values represent: mean ± standard division (n = 6); PDI: Poly dispersive index; EGCG: epigallocatechin-3-gallate; NPs: nanoparticles; RGD: arginine-glycine-aspartic acid; GE: Gelatin/EGCG self-assembling NPs; GEH: GE NPs with hyaluronic acid (HA) surface coating; GEH-RGD: GE NPs with HA-RGD surface decoration.
