Theranostics gold nanoparticles

Theranostic nanoparticles with gold can be made with other metallic nanoparticles such as SPIONs, for providing multi-imaging modality and dual therapeutic outcomes. A recent study showed that gold and SPIONs loaded in an amphiphilic diblock copolymer PEG-fo-PCL had selective tumor accumulation, enabling MRI of the tumor margins and improved survival rate of tumor-bearing mice after NIR irradiation [82].
