Novel hyaluronic acid-modified temperature-sensitive nanoparticles for synergistic chemo-photothermal therapy

This study has developed a versatile nano-system with the combined advantages of photothermal effect, active tumor-targeting, temperature-sensitive drug release, and photoacoustic imaging. The nano-system consists of the core of the phase change material (PCM), the outer polypyrrole (PPY) shell and the hyaluronic acid (HA) modified in the PPY shell. The obtained composite nanoparticles (denoted as DTX/[email protected]@HA) were spherical with a...
