A carrier-within-a-carrier system with calcium nanoparticles encapsulated in β-cyclodextrin-polysaccharide hydrogel for verteporfin delivery and radiosensitization in orthotopic osteosarcoma.
A pH-responsive hydrogel reservoir is developed by integrating verteporfin (VP)-loaded CaCO3 nanoparticles (CaNPs) into a β-cyclodextrin-crosslinked polysaccharide hydrogel to achieve precise radiosensitization and immunomodulation, offering a promising approach to overcoming radioresistance and improving therapeutic o...
