Abstract
Schematic presentation of synthetic procedure of HA-FCNs (a) and HA-FCNs/ACP (b). • The great prospects in cancer treatment of multifunctional nanoparticles. • pH responsive drug release behavior and excellent biocompatibility. • Targeted into human lung cancer cells (A549 cells). • Stronger fluorescence signals. Recently, multifunctional nanoparticles have shown great prospects in cancer treatment, which have the ability to simultaneously deliver the drug, image and target tumor cells. In this paper, we designed a luminescent nanoparticles platform based on hydrothermal hyaluronic acid/amorphous calcium phosphate (HA-FCNs/ACP) with multifunctional properties for drug delivery, bio-imaging, and targeting treatment. HA-FCNs/ACP shows an ability to load curcumin (Cur) with pH-sensitive responsive drug release behavior and excellent biocompatibility. HA-FCNs/ACP dispersed in the cytoplasm through the overexpressed CD44 receptor that is actively targeted into human lung cancer cells (A549 cells). Meanwhile, the viability of A549 cells was significantly inhibited in vitro . The prepared HA-FCNs and HA-FCNs/ACP both exhibit excellent targeted bioimaging performance on cancer cells. Hence, the as-prepared nanoparticles have promising applications in treating tumor disease.
