For example, Cho et al. [144] used hyaluronic acid-ceramide- (HA-CE-) based self-assembled nanoparticles for the selective delivery of docetaxel (DET) to the CD44-overexpressing cell line (MCF-7) and concluded that the HA-CE-based nanoparticles might be a good anticancer drug delivery system through passive and active tumor targeting. Here, CD44 is linked to neoplasm.
