Summary of EGCG delivery systems: (1) grafting EGCG on the surface of the nanoparticles to enhance cellular uptake of as-obtained nanovehicles; (2) surface functionalization with specific molecules (chitosan, folic acid, gallic acid, and chlorogenic acid) to enhance stability, cellular uptake, and drug release properties of the nanovehicles; (3) targeted molecular modification by peptides or aptamers to target specific cancer cell receptors; (4) construction of multi-modal therapeutics co-delivery systems to realize EGCG-involved cancer combination therapy.
